5. Which type of wave on the electromagnetic spectrum has the longest wavelength?

Gamma Wave

Radio Wave

Infrared Wave

Microwave

Radio waves have the longest wavelengths and therefore, the lowest frequency.

Explanation

Radio waves have the longest wavelengths and therefore, the lowest frequency.

6. Ultraviolet light (UV light) has a smaller wavelength and a higher energy than colors in the visible light spectrum.

True

False

UV light has a smaller wavelength than the visible light spectrum. This means that the wavelengths are very close together. As a result, the wave is travelling fast and is carrying a lot of energy. Remember that UV light comes before violet and Infrared comes after red.

7. Please list the waves of the Electromagnetic Spectrum in order beginning with the waves with the shortest wavelength (Gamma Waves) and ending with the waves with the longest wavelength (Radio Waves).

Gamma Waves

Radio Waves

Microwave

X-Rays

Ultraviolet Waves

Infrared Waves

Visible Light Spectrum

Remember that the Electromagnetic Spectrum begins with Gamma Rays (shortest wavelength), then X-Rays, Ultraviolet, Visible Light Spectrum, Infrared, Microwaves, and finally, Radio Waves (longest wavelength).

8. Which term below describes the maximum height of a wave from the resting position?

Amplitude

Trough

Wavelength

Frequency

Amplitude is the maximum height of a wave from the resting position.

Explanation

Amplitude is the maximum height of a wave from the resting position.

9. Which word below describes the relationship between wavelength and frequency?

Exponential relationship

Linear relationship

Conjoined relationship

Inverse relationship

An inverse relationship shows that one variable increases if another variable decreases. In the case of wavelength and frequency, as wavelength decreases, frequency increases.

Explanation

An inverse relationship shows that one variable increases if another variable decreases. In the case of wavelength and frequency, as wavelength decreases, frequency increases.

10. A wave has a frequency of 60 Hz and a wavelength of 10 m. What is the velocity of the wave? Hint: F=V/Wavelength

6 m/s

0.6 m/s

600 m/s

6,000 m/s

You can rearrange the formula to solve for velocity: Velocity = frequency multiplied by wavelength. So the answer is 6*10 = 600 m/s. Please also know how to rearrange the formula to solve for frequency and/or wavelength.

Explanation

You can rearrange the formula to solve for velocity: Velocity = frequency multiplied by wavelength. So the answer is 6*10 = 600 m/s. Please also know how to rearrange the formula to solve for frequency and/or wavelength.

11. Light exhibits qualities of both particles and waves. What type of wave below describes how light moves?

Longitudinal

Transverse

Amplitude

None of the above

Sound is a longitudinal wave that operates in a series of compressions and rarefactions. Light moves as a transverse wave.

Explanation

Sound is a longitudinal wave that operates in a series of compressions and rarefactions. Light moves as a transverse wave.
