Wave motion and geometrical optics

Question 1

Mechanical waves

Answer 1

This type of wave needs to travel through something and does it through the vibration of particles. There are standing waves which move away from its source

Question 2

Electromagnetic waves

Answer 2

Move on its own without a medium to carry it

Question 3

Parallel to energy flow

Answer 3

longitudinal

Question 4

Perpendicular to energy flow

Answer 4

transverse

Question 5

Regions in which the medium is stretched out

Answer 5

rarefaction

Question 6

medium

Answer 6

any material, substance, or space which light can be transmitted through

Question 7

Maximum displacement upward

Answer 7

crest

Question 8

Maximum displacement downward

Answer 8

trough

Question 9

Amplitude

Answer 9

maximum displacement from equilibrium position

Question 10

Frequency

Answer 10

Number of waves that pass through a point in one second (Hz)

Question 11

Period

Answer 11

the time between one event

Question 12

Wavelength

Answer 12

distance between one crest to the next

unit= lambda

Question 13

universal wave equation

Answer 13

v = (lambda) f
