WorksheetsSound Waves and Light Waves
Total questions: 20
Worksheet time: 8mins
When I speak in a high-pitch voice, the sound waves have
high amplitude
low amplitude
high frequency
low frequency
When I speak with low energy, the sound waves have
low frequency
low amplitude
short wavelength
high amplitude
Frequency and Wavelength have inverse (opposite) relationships!
True
False
Waves with a low frequency must have
low amplitude
long wavelength
short wavelength
low energy
To decrease the amplitude, I should
draw shorter waves
draw "smaller" waves
draw less waves
draw waves with a longer wavelength
To increase the frequency, I should
draw taller waves
draw waves with a longer wavelength
draw waves with more energy
draw more waves
Frequency is related to the volume and the amount of energy in a sound wave.
True
False
A sound wave has a long wavelength. This wave has
loud volume
high pitch
low pitch
soft volume
Daniel enters a cave and starts singing. He hears a repetition of his song caused by the bouncing of sound waves from the cave walls. This is an example of ______.
echolocation
reflection
refraction
an echo
Echolocation helps animals survive by helping them
locate their prey.
warn their prey.
see their prey.
play with their prey.
_____ is electromagnetic waves that can be detected by the eye.
Energy
Matter
Sound
Light
Lights are always reflected off the surface of objects.
True
False
Refraction occurs when
light bounces off an object, changing direction
light bends as it passes from one medium to another
light is absorbed by an object
Never! Light is never refracted!
Nathan has black hair. On a hot summer day, the top of his head will
feel the same
feel very curly
feel very hot
feel very cool
This is showing
light absorption
echolocation
light refraction
light reflection
Light waves do NOT need a medium to travel.
True
False
Sound waves DO need a medium to travel because
sound waves always have high amplitude.
sound can only travel through gas.
sound can only travel through liquid.
sound requires vibration.
In order to see, light waves must be detected by the _______ in the retina.
sense adaptors
sense receptors
sense antennas
sense reflectors
The eye is the only part of the body that has sense receptors.
True
False
______ is a vibration that travels as a wave through a medium.
Sound
Light
Matter
Energy
