Waves

Question 1

longitudinal waves examples

Answer 1

sound waves (ultrasound)
shock waves (seismic)

Question 2

transverse waves examples

Answer 2

electromagnetic waves
ripples in water
waves on a string

Question 3

longitudinal waves

Answer 3

oscillations are parallel to the direction of energy transfer

Question 4

transverse waves

Answer 4

oscillations are perpendicular the the direction of energy transfer

Question 5

equation for wave speed

Answer 5

wave speed = frequency x wavelength

m/s = Hz x m

Question 6

equation for a period

Answer 6

1/frequency

Question 7

amplitude

Answer 7

maximum displacement of a point on the wave from its undisturbed position

Question 8

wavelength

Answer 8

distance between the same point on two adjacent waves (from trough to trough)

Question 9

frequency

Answer 9

number of complete waves passing a point per second

Question 10

name the two types of reflection

Answer 10

specular

diffuse
