Which of the following is not an example of a mechanical wave?
Light wave
Sound wave
Water wave
Seismic wave
How is an electromagnetic wave different from a mechanical wave?
An electromagnetic wave travels slower than a mechanical wave.
An electromagnetic wave has a larger amplitude than a mechanical wave.
An electromagnetic wave can travel through a vacuum, but a mechanical wave cannot.
An electromagnetic wave has no wavelength, but a mechanical wave has a wavelength.
Which of the following are not a part of the Electromagnetic Spectrum?
Gamma Rays
Radio waves
Magnetic waves
x-rays
Gamma Rays are
High energy
Low energy
Medium energy
Just right
A light wave is considered to be an electromagnetic wave. But what other kind of wave is it?
Surface wave
Longitudinal wave
Transverse wave
What is ultraviolet light
Light that has more energy than regular light so we can't see it.
Light that has less energy than regular light so we can't see it.
Light that is only given off at night.
Light that only All Might can see.
A wave with a large wavelength will have a ______ frequency and _____ energy
high, low
high, high
low, high
low, low
Which section of the spectrum is the ONLY one we can see?
X-rays
Visible Light
Gamma Rays
Ultraviolet Rays
The color of a light corresponds to the
amplitude
frequency
When you change the pitch of the wave, the __________ of the wave is changing.
wavelength
amplitude
crest
trough
What does this piece of evidence from the "What is Melanin?" article prove? (check ALL that apply)
The genetic material in skin cells with more melanin absorbs less UV light from the sun.
The genetic material in skin cells with less melanin absorbs more UV light from the sun.
Melanin absorbs UV light from the sun, which can keep some UV light from reaching genetic material.
UV light is attracted to skin cells.
The genetic material in skin cells with more melanin absorbs more UV light from the sun.
1. If a car sits out in the sun every day for a long time, can light from the sun damage the car’s paint?
Yes. The paint can take in energy from the light, causing it to be damaged.
No. Light can only change things by warming them up, so it cannot damage the car’s paint.
No. Light is not a physical thing, so it cannot change physical things like paint.
Yes. Light from the sun can pull energy out of the paint, causing it to be damaged.
How are we able to perceive an object as being the color white?
All colors of visible light are absorbed by an object and then reflected into our eye.
All colors of visible light are reflected off an object and then to our eye.
All colors of visible light are absorbed by an object and no light is being reflected into our eye.
In order to see an object, light must be
transmitted into your skin
reflected off the object and into your eyes
reflected off the object then off the ground then into your eyes
absorbed by your genetic material
Which statement best describes the relationship between the frequency
and the wavelength of waves?
As frequency increases, wavelength gets longer.
As frequency increases, wavelength gets shorter.
As wavelength decreases, frequency remains the same.
As wavelength changes, there is no change in frequency.
Which statement best describes visible light?
The human eye can only detect visible light as white light.
Visible light can only be seen with special equipment or technology.
Visible light makes up a small part of the electromagnetic spectrum.
The frequency of visible light is the same as the frequency of gamma rays.
A ____________ object does allow a few light waves to pass through it.
light
translucent
opaque
long
What property of light allows humans to detect differences in color?
the intensity of light the eye receives
the wavelength of the light the eye receives
the speed at which the light wave travels to the eye
the distance the light wave travels from the source to the eye
