B. Pulses & Periodic Waves

 

1. Pulse – single vibratory disturbance that moves from point to point

 

 

Medium only moves up and down

Ex)

 

 

In which direction will segment X move as the wave passes through it?

(1) down, only (2) up, only

(3) down, then up, then down

(4) up, then down, then up

 

 

 

 

(4) up, then down, then up

 

 

When the light waves hit the surface of the bubble
it does 2 things. Name them

Answer: When the light hits the surface of the bubble, sof the light is transmitted and some is reflected

 

 

a. When the pulse (wave) reaches a boundary with another medium, part is reflected and part is transmitted (goes through)

b. When a pulse reaches a fixed, unyielding boundary, then the pulse is completely reflected and inverted (180°)
