Question

A Guide on Waves

Answer 1

Waves are visble and non-visble, they can be heard and not heard. Waves are different in any sort of way there are Ocean waves, Radio waves, Micro waves, X-rays, Eletromagnetic Waves, Ect.

Answer 2

Waves have a high frequency Which is when you see the waves on a diagram bigger and closer to one another, There is also low frequency, Which is when u see the waves smaller and father apart from each other on a diagram.

Answer 3

Mechanical Waves
Mechanical waves travel though some sort of matter called a medium. They travel when molecules in the medium collide with each other and pass on energy. So, mechanical waves can’t travel through a vacuum, which is space that has no matter in it. Sound is a type of mechanical wave. It can travel through gases, liquids, or solids, but not through a vacuum. Water waves, seismic (earthquake) waves, and waves traveling through a spring or string are other examples of mechanical waves.

Answer 4

Electromagnetic Waves
The motion of charged particles creates electromagnetic waves. The motion causes a disturbance that travels in the form of moving electric and magnetic force fields. Each field creates the other, so no medium is needed. Electromagnetic waves can travel through a vacuum. For example, electromagnetic waves travel from the Sun to Earth through the vacuum of space. Examples of electromagnetic waves are visible light, microwaves, radio waves, and x-rays. Although mechanical waves and electromagnetic waves are different in some ways, both carry energy.

Answer 5

Wave Measurements
So, how can we tell one wave apart from the next? We can assign numerical values to certain aspects of waves in the form of wave measurements. These measurements relate to wave characteristics. Let’s look at sound as an example. In sound, pitch depends on wave frequency. Loudness depends on wave amplitude. In addition to frequency and amplitude, we can measure several other aspects of waves.

Answer 6

PARTS OF A WAVE
crest– the highest part of a wave
trough– the lowest part of a wave
amplitude– the wave height measured from the equilibrium position to the crest or trough
wavelength– the distance measured between two adjacent crests or troughs
frequency– the number of waves created per second
Amplitude relates to the energy of the disturbance. The higher the amplitude of a wave, the more energy it has. A loud sound wave has a higher amplitude than a quiet sound wave. A destructive tsunami wave has a higher amplitude than a normal ocean wave.

Frequency relates to how quickly the disturbance occurs. Frequency is the number of waves, or cycles, per second. The unit of cycles per second is hertz (Hz).

Answer 7

As waves travel, they encounter a number of materials. Some materials let waves travel through, but others absorb all of the wave’s energy. When a wave travels through a material, it loses a small amount of energy as heat. Eventually, the wave will stop when it loses all of its energy.

When guitarists play in a recording studio, they create strong sound waves. The air and the floor allow the sound waves to pass through them. Other materials in the studio, such as furniture, absorb the sound waves. Materials called sound dampeners are used in studios to absorb the sound. Although sound waves pass through the air and floor, they’ll eventually lose their energy and fade away.

Answer 8

Waves move with a certain speed. The speed of a wave, v, is the product of its frequency, f, and wavelength, λ. So, if wavelength increases, frequency decreases, and vice versa.

v = f λ

For a given type of wave and medium, the speed of the wave is constant through that medium. Consider sound waves. For any sound wave traveling in the air, each point travels 343.2 meters in one second. However, the speed of the wave changes if the medium changes. In water or on the ground, the molecules are packed more tightly than they are in the air. So, sound waves travel much faster in water and on the ground. In the image, a mechanic uses a stethoscope attached to a probe to listen to problematic sounds from the engine. Because sound from the engine reaches the mechanic more quickly in metal than it does in air, he can better pinpoint where the sound is coming from.

When a wave travels, its frequency never changes. When a wave moves from one medium to another, its wavelength and speed change, but not its frequency.

Answer 9

Waves can have different shapes. The differences in wave shapes are due to the direction of the disturbance as the wave travels. Waves in which the disturbance moves at right angles to the direction of the wave are called transverse waves. The string of beads shown in the simulation is a transverse wave. In transverse waves, the disturbance moves up and down as the waves move horizontally. Seismic waves are also transverse waves.Waves in which the disturbance moves in the same direction as the waves are called longitudinal waves. Longitudinal waves are also known as compression waves. Sound waves are longitudinal. In a sound wave, air molecules collide with each other in the direction of the wave’s movement. If we compress one end of a spring and let go, the coil moves from left to right as the wave travels. So, a wave that moves through a spring this way is also a compression wave. Water waves are a combination of transverse and longitudinal waves. As a result, the water molecules travel in an oval-shaped path.

Answer 10

Electromagnetic waves have an interesting shape, which can be difficult to draw. In the video on radio waves, the electric and magnetic fields grew and shrank as the wave moved outward from its source.

We can show the two fields as two transverse waves that travel together and are at right angles to each other. Look at the image of a double transverse wave. Here, one wave (in blue) shows the change in the amount of the electric field. The other wave (in red) shows the change in the amount of the magnetic field.

Answer 11

Although waves can have different shapes, we use a standard wave format to show the measurements of a wave. This approach makes it easier to interpret and compare waves. The standard wave format is a single transverse wave, and it describes the characteristics and measurements of any wave. Although a sound wave isn’t a transverse wave, it’s still represented in this format. Recall that the bead string simulation earlier in the lesson was in the standard wave format.

Answer 12

In sound waves, changing the wavelength creates a sound with a different pitch. Changing the amplitude changes the loudness. When we speak, we create these differences in sound waves. Our ears hear the different sounds as words and sentences. Sound is one way that we communicate with each other. Our ears can distinguish these differences in sound waves that correspond to words and musical notes. The sound waves encode information. However, sound waves can travel only a short distance before they’ve been absorbed or have lost all their energy. So, sound doesn’t work as a form of communication when people are far apart from each other.In contrast, radio waves can travel much farther and faster than sound waves. Like sound waves, radio waves can vary in wavelength and amplitude. So, we use technology and radio waves to send and receive information over long distances. Our wireless devices convert between radio waves and words, music, and pictures.
