(17 cards)
sound waves..
require a medium
light waves ..
are electromagnetic waves
the wavelength of the wave in the diagram is
1.5 m
a man is standing on the shore of a beach up to his knees in water. every 5 seconds a wave breaks on him. what is the period?
5 seconds
a train of waves is moving at a speed of 30 m/s. the frequency of the waves is 10 Hz. what is the wavelength?
3 m
how loud a sound is depends on
the amplitude of the waves
a _______ is a good mathematical model for representing transverse waves
sine curve
the color light is determined by ______ of the light waves
the frequency
the wave with a frequency of 0.5 Hz and a speed of 10 m/s has a wavelength of
20 m
(T/F) A wave transports energy but not matter.
true
(T/F) Light waves require a medium in which to travel.
false - don’t require
(T/F) Sound waves are examples of longitudinal waves.
true
(T/F) As the frequency of found waves increase, the wavelength of the sound waves decreases.
true
(T/F) The color of visible light depends on the wavelength of the light
true
(T/F) When two waves are in the same place at the same time, the combine to produce a single waves
true
(T/F) Nodes in a standing wave are the results of constructive interference
false- destructive
when light passes from air to glass, the light may change direction due to reflection
false- refraction
