Q

what is frequency units

A

hertz- Hz

17
Q

what is frequency equation (2 ways)

A

1/T or V/lambda

18
Q

what is period and its equation

A

time in seconds for 1 wave to pass a point
period=1/f

19
Q

what is wavespeed
2 ways

A

speed at which the wave moves through the medium or speed at which energy is transferred

20
Q

what is wavespeed equation

A

v=fxwavelength

21
Q

what is rarefaction of waves

A

waves can change direction when they change speed - moving from one medium to another

22
Q

what happens when light passes from air into glass

A

the velocity of light decreases causing the direction of the waves to change

23
Q

what happens when waves pass from the glass back to the air

A

their velocity increases causing the image to appear as shifted position

24
Q

when can rarefaction happen

A

when any waves change speed as it passes from one medium to another

25
Q

what is the exception to the rarefaction rule

A

if waves enter or leave the medium at right angles to the surface they do not change direction
