(5.1.1) Wave Basics

Question 1

What does a wave do?

Answer 1

Transfer energy without moving matter

Question 2

What are the 2 types of wave

Answer 2

Longitudinal and transverse

Question 3

What is a longitudinal wave?

Answer 3

Type of wave where they transfer their energy (propagate) by oscillations where particles of the medium vibrate parallel to the direction of travel

Question 4

What is a transverse wave?

Answer 4

Type of wave where they transfer their energy (propagate) by oscillations where particles of the medium vibrate perpendicular to the direction of travel

Question 5

What are some examples of longitudinal waves?

Answer 5

Sound waves, Ultrasound waves and P-waves (Earthquake shock waves)

Question 6

What are some examples of transverse waves?

Answer 6

Water waves and the electromagnetic spectrum

Question 7

What is the amplitude of a wave?

Answer 7

The max height of the wave

Question 8

What is a period of a wave?

Answer 8

The time for one complete cycle of oscillations for the waves

Question 9

What is a wavelength?

Answer 9

Distance between 2 corresponding points on a wave

Question 10

What is the frequency?

Answer 10

Number of cycles of the wave passing through the same point in the medium per second

Question 11

What does intensity mean?

Answer 11

A measure of how much energy a wave carries

Question 12

What is intensity as an equasion?

Answer 12

1/ (Distance)^2

Question 13

What is intensity proportional to?

Answer 13

The square of the amplitude
