Waves

Question 1

What are the 2 types of waves

Answer 1

Transverse and longitudinal

Question 2

Describe the oscillations of transverse waves

Answer 2

Oscillations are 90 degrees (perpendicular) to direction of travel.

Question 3

Where is the wavelength on a transverse wave

Answer 3

Between 2 peaks/troughs

Question 4

What does the amplitude of a transverse wave mean

Answer 4

How quiet/loud the wave is

Question 5

What does the frequency of a transverse wave mean

Answer 5

How many waves pass a point in a second

Question 6

What are the units for frequency

Answer 6

Hz

Question 7

Draw a labelled diagram of a transverse wave

Question 8

Name and example of a transverse wave

Answer 8

Light and electromagnetic waves

Question 9

What would the change in frequency in a light wave affect

Answer 9

It would affect the colour/change the colour in the spectrum

Question 10

Describe the oscillations in a longitudinal wave

Answer 10

The oscillations are parallel to the direction of travel

Question 11

Name and example of a longitudinal wave

Answer 11

Sound and p waves

Question 12

Question 13

Why dont sound waves travel in space

Answer 13

because space is a vacuum, therefore has no particles. And sound waves travel by sound bouncing off of particles.

Question 14

What state of matter do sound waves travel faster through and why?

Answer 14

Solids, because the particles are close together, therefore the sound particles can pass through the particles easy/quickly.

Question 15

Draw the triangle for wave speed, distance and time
