Electromagnetic Spectrum Waves

This diagram shows the magnetic spectrum. What statement best compares a gamma ray to a radio wave?

• A gamma ray has more energy than a radio wave because it has a longer wavelength and a lower frequency.

• A gamma ray has more energy than a radio wave because it has a shorter wavelength and a higher frequency.

• A gamma ray has more energy than a radio wave because it has a shorter wavelength and a lower frequency.

• A gamma ray has more energy than a radio wave because it has a longer wavelength and a higher frequency.

Lapis is studying the relationship between the energy transferred by electromagnetic waves and their wavelengths using this diagram. How does she describe this relationship? (Select all that apply.)

• Radio waves have a small wavelength and a large amount of energy.

• Gamma rays have a large wavelength and a small amount of energy.

• Gamma rays have a small wavelength and a large amount of energy.

• As the wavelength decreases, the energy decreases.

• As the wavelength increases, the energy decreases.

Osiris creates the following table of the energy in different electromagnetic waves, measured in electron volts. The chart shows the relative wavelengths of various types of electromagnetic waves. Which type of electromagnetic wave belongs in the cell labeled with a question mark?

• Ultraviolet wave, because an ultraviolet wave has a shorter wavelength than both infrared and X-rays, so it has less energy.

• Gamma ray because a gamma ray has a shorter wavelength than both infrared and X-rays so it has less energy.

• Radio wave because a radio wave has a longer wavelength than both infrared and X-rays, so it has less energy.

• Visible light, because a visible light wave has a longer wavelength than both infrared and X-rays, so it has less energy.

This diagram shows three types of electromagnetic radiation and their range of frequencies. Which explanation correctly uses the data in the diagram to show how infrared radiation and ultraviolet radiation are related in terms of energy?

• Ultraviolet radiation has more energy that infrared radiation because energy is proportional to frequency and the frequency of ultraviolet radiation is higher.

• Ultraviolet radiation has less energy than infrared radiation because energy is proportional to frequency and the frequency of ultraviolet radiation is lower.

• Ultraviolet radiation has more energy that infrared radiation because energy is inversely proportional to frequency and the frequency of ultraviolet radiation is lower.

• Ultraviolet radiation has less energy than infrared radiation because energy is inversely proportional to frequency and the frequency of ultraviolet radiation is higher.
