A pulse is created on a spring with a fixed end. What happens to the wave after it hits the fixed end? a. it reflects , remains upright , and maintains the same velocity b. it reflects , reverts and maintains the same velocity c.it refects, remains upright and changes velocity d, it reflects , reverts and changes velocity
it reflects, speed remains the same, reverts
so is it a , b , c or d?
b. but they have use wrong term. because velocity changes not speed. so it can be d
ok
its not d lol i guess it was b oh well next question
Two waves with equal amplitude meet each other, resulting in a wave with zero amplitude. Which phenomenon explains this resultant?
a. diffraction b. reflection c. refraction d. interference
interference.
correct next
A wave is traveling from one medium to another. If the wave is partially transmitted and partially reflected from the boundary, what will happen to the amplitude of the reflected wave?
a. it will have less amplitude then the incident wave b.it will have the same amplitude as the incident wave c.it will have more amplitude then the incident wave d.its amplitude will be zero
just write a b c or do i want yu to save yur typing wen yu write
a, b , c or d
i'm not sure. b
ok
hold on
Two waves with amplitudes of 75 units and 74 units arrive at a point in a medium simultaneously. If the two waves are out of phase with each other, what is the resultant amplitude of the wave?
a.74units b.1unit c.75units d.149units
they are out of phase by how much angle.
A wave is traveling from one medium to another. If the wave is partially transmitted and partially reflected from the boundary, what will happen to the amplitude of the reflected wave?
remains same
hold on real quick
A wave is incident on the surface of a mirror at an angle of 41° with the normal. What can you say about its angle of reflection? A. is it less than the angle of indience b.is it equal to the angle of indience c. is it greater than the angle of indience d. is it zero , as it reflects along the normal
b
