Waves and Energy Review 5

Which best describes the relationship between waves and matter?

• All waves require matter in order to transfer energy.
• Mechanical waves require matter to transfer energy, but electromagnetic waves do not.
• Electromagnetic waves require matter to transfer energy, but mechanical waves do not.
• All waves transfer matter using energy.

• Radio waves
• Gamma rays
• X-rays
• Ultraviolet rays

What type of electromagnetic wave is used in night vision and thermal imaging?

• X-rays
• Infrared
• Ultraviolet
• Radio waves

Which type of electromagnetic wave has the highest energy?

• Microwaves

Which of the following pictures is depicting a transverse wave?

• 
• 
• 

The __________ of a wave is how many wavelengths pass a fixed point each second.

• Amplitude
• Wavelength
• Frequency
• Speed

Which wave has the highest frequency?

• Wave A
• Wave B
• Wave C

Which of the following would be true if a wave's frequency increased?

• the wave's amplitude would be lower
• the wave's amplitude would be higher
• the wave's wavelength would shorten
• the wave's wavelength would lengthen

How are these two waves different?

• The amplitude of Wave 2 is twice the amplitude of Wave 1.
• The wavelength of Wave 2 is twice the wavelength of Wave 1.
• The frequency of Wave 2 is twice the frequency of Wave 1.

Which of the following waves would have the most energy and why?

• Wave A because it has the longest wavelength
• Wave B because it has the highest amplitude
• Wave C because it has the shortest wavelength
• Wave D because it has the lowest amplitude
