Waves

Question 1

What is the difference between light and sound waves?

Answer 1

Light is faster, sound is vibrations of particles, sound can’t travel in a vacuum, light is vibrations of electric and magnetic fields (an electromagnetic wave)

Question 2

What are the similarities of light and sound waves?

Answer 2

They both can reflect and refract, both are made by vibrations, both can transfer energy and information

Question 3

What are waves

Answer 3

A method to transfer energy but it DOESN’T transfer the material, only the energy

Question 4

What is a longitudinal wave

Answer 4

Waves where the medium( material or matter) vibrates in the same direction the wave travels in

Question 5

What is a transverse wave

Answer 5

Waves where the medium( material or matter) vibrates perpendicular to the direction the wave travels in

Question 6

What are some examples of longitudinal waves

Answer 6

Sound, pressure, shock, slinky toy

Question 7

What are some examples of transverse waves

Answer 7

Light, water, rope, electromagnetic radiation

Question 8

What is the wave’s peak

Answer 8

The highest part of the wave

Question 9

What is the trough of the wave

Answer 9

The lowest part of the wave

Question 10

What is the amplitude of the wave

Answer 10

The peak or trough to the ‘middle’ of the wave

Question 11

What is the wavelength of the wave

Answer 11

The length of peak to peak or trough to trough
