Question 2

What is a transverse wave?

Answer 2

A transverse wave is where the vibrations are in the same direction as the direction of the wave

Question 3

What are the 3 wave equations?

Answer 3

V=F* λ
λ=F/V
F=V/λ

Question 4

What are the 3 d, v and t equations

Answer 4

D=V*T
V=D/T
T=D/V

Question 5

What is used to look at waves?

Answer 5

An oscilloscope

Question 6

How is sound produced?

Answer 6

Sound is produced when things vibrate
