9. General Wave Properties I

Question 1

what are the 2 types of waves?

Answer 1

1. Transverse waves where the direction of vibration is perpendicular to direction of wave
2. Longitudinal waves where the direction of vibration is parallel to the direction of wave

Question 2

What is the amplitude of the wave’s graph?

Answer 2

maximum magnitude of displacemet

Question 3

Is crest the highest or lowest point?

Answer 3

highest point

Question 4

what is the opposite of crests?

Answer 4

troughs

Question 5

Define Wavelength

Answer 5

The shortest distance between 2 successful crests or troughs

Question 6

What is a phase?

Answer 6

The 2 points have the same direction of motion

Question 7

Frequency formula

Answer 7

Frequency= 1/time take for 1 oscillation to happen

Question 8

Wave speed formula

Answer 8

1. Wave speed= wave length/ time taken
2. Wave speed= frequency x wavelength

Question 9

2 property of mediums

Answer 9

1. Wave frequency remains unchanged
2. Since frequency remains unchanged, wavelength changes hence speed changes too

Question 10

What are wavefronts?

Answer 10

They are imaginary line that joins all adjacent points together
