Question

Two waves with an amplitude of 54 units and 64 units arrive at a point in a medium simultaneously. If the two waves are in phase with each other, what is the resultant amplitude of the wave?

Answer 1

i think the amplitudes will add up.ie 120 units.

Answer 2

can you tell me the formula that you used

Answer 3

take a string and consider what'll happen in this situation.amplitude simply gets added up when two waves collide.

Answer 4

ooooooh

Answer 5

what about 118
units

Answer 6

yeah 118

Answer 7

amplitudes that are exactly in phase will add, amplitudes out of phase will partially add, but the math gets more complicated.

Answer 8

ok so what about when an object goes through water is it refraction diffraction, reflection, or interfernce?

Answer 9

and it bends

Answer 10

it can't be interference if it's only 1 wave

it can't be reflection, because then the water would be a mirror

it's not diffraction because the wave doesn't split

Answer 11

so basically its refraction?

Answer 12

yup

Answer 13

so when water waves travel around the edges of boats is that diffraction?

Answer 14

like the bottom of the boats

Answer 15

no, that's just the displacement of water around the boat

Answer 16

there's a big difference between light waves traveling through water and big objects like rocks and boats moving through water

Answer 17

n a harbor, you can see sea waves traveling around the edges of small stationary boats. Why does this happen? <<<<<<<"this is the question"

Answer 18

and the answers are diffraction reflection refraction and transmission

Answer 19

in open water the wave front moves in essentially a straight line. when it hits an object in its path, it must bounce off the object

Answer 20

and i thought it would b diffracrtion.

Answer 21

diffraction is the splitting of waves into separate waves of different frequencies, like when a prism splits white light into a rainbow

Answer 22

so is it like reflection like when light travels in a straight like and it bounces of a mirror and go the opposite way like the water bounces off the boat and is disturbed and goes the opposite way.

Answer 23

yep, pretty much
