Gamma rays have the shortest wavelength of the electromagnetic waves. Which of the following is also true of gamma rays?
They are visible to humans.
They have the highest energy.
They have the lowest frequency.
They are only emitted by the Sun.
Visible light and ultraviolet (UV) light are both forms of electromagnetic radiation, and waves of each travel at the same speed. Human eyes are unable to see UV light because it is not in the visible range of the electromagnetic spectrum. If the frequency of one UV light wave is twice that of a visible light wave, how will their wavelengths compare?
The wavelength of the UV light wave will be half that of the visible light wave.
The wavelength of the UV light wave will be twice that of the visible light wave.
The wavelength of the UV light wave will be four times that of the visible light wave
A.The wavelength of the UV light wave will be the same as that of the visible light wave.
Francesca is drawing a picture of the electromagnetic spectrum. She needs to order the types of electromagnetic radiation from the lowest to highest frequency. Which of the following shows the correct order of the electromagnetic spectrum, from lowest to highest frequency?
A.visible, UV, infrared, X-ray, microwave, radio, gamma
A.radio, visible, microwave, infrared, UV, X-ray, gamma
A.gamma, UV, microwave, infrared, radio, X-ray, visible
A.radio, microwave, infrared, visible, UV, X-ray, gamma

Why can you see illuminated objects?
Your eyes detect light emitted by the object
Your eyes detect light absorbed by the object
Your eyes detect light refracted by the object
Your eyes detect light that reflects of the object
Which of the following happens during reflection, absorption, scattering, and transmission?
Light travels through empty space
Light energy turns into chemical energy
Chemical energy turns into light energy
light interacts with matter
An interaction of light with matter that causes light to change direction is called
scattering
luminosity
absorption
illumination

in three directions
in a circular motion
in straight lines
in wavy lines

Why does Mr. Downes jacket have a red appearance?
It's his favorite color
ROY G BIV
Red light is absorbed and the rest is reflected
Red light is reflected and the rest is absorbed
