Electromagnetic Spectrum - SC.7.P.10.1

(SC.7.P.10.1) The illustration below shows what happens when light is passed through a prism. What type of light passed through the prism?

• infrared light
• ultraviolet light
• white light
• yellow light

(SC.7.P.10.1) Radio waves have a different wavelength than X-rays. Yet, both radio waves and X-rays travel as electromagnetic radiation through the vacuum of space at the same speed. Why?

• Radio waves have a shorter wavelength than X-rays.
• Radio waves have the same frequency as X-rays.
• All electromagnetic radiation travels at the same speed through space.
• Radio waves and X-rays interact with each other.

(SC.7.P.10.1) When NASA scientists communicate with the mars rover, shown in the illustration, they use electromagnetic radiation with a long wavelength and low energy. Which type of radiation do they most likely use?

• X-rays
• radio waves
• infrared waves
• visible light

(SC.7.P.10.1) Visible light is made up of a spectrum of many different colors as shown in the illustration below. Which color of visible light has the longest wavelength in nanometers (nm)?

• blue
• yellow
• violet
• red

(SC.7.P.10.1) How is white light different from the rest of the electromagnetic spectrum?

• White light has the same wavelength.
• White light has a spectrum of colors.
• White light can travel through both empty space and matter.
• White light is invisible.

(SC.7.P.10.1) The illustration below shows the different colors and wavelengths of visible light. Blue-green light can be found in what wavelength nanometer (nm) range?”

• 400 nm – 490 nm
• 575 nm – 700 nm
• 425 nm – 576 nm
• 575 nm – 585 nm

(SC.7.P.10.1) White light is made up of a spectrum of many different colors. What property is used to divide the various colors in the spectrum?

• density
• wavelength
• speed
• temperature

(SC.7.P.10.1) How is ultraviolet light different from the light emitted by a flashlight?

• Ultraviolet light is brighter than the light from a flashlight.
• Ultraviolet light is invisible to the human eye.
• Only light from a flashlight can travel through a vacuum.
• Ultraviolet light has a longer wavelength than the light from a flashlight.

(SC.7.P.10.1) The electromagnetic spectrum consists of all the wavelengths of radiation that come from the sun. What can electromagnetic waves do that sound waves cannot do?

• change frequency
• travel through a solid object
• travel through a vacuum
• change wavelength

(SC.7.P.10.1) The sun’s energy arrives as radiation. Which statement about electromagnetic radiation is correct?

• All radiation is visible.
• Radiation travels faster than the speed of light.
• Radiation is the transfer of energy as waves.
• All radiation is invisible.
