• Crest

• Amplitude

• Wavelength

How would you measure wave length?

• Point C to D

• Point B to F

• Point A to B

• Point D to E

What type of wave is this?

• Transverse

• Longitudinal

• Compression

• Sound

What type of wave is this?

• Transverse

• Light Wave

• Surface Wave

• Longitudinal Wave

Which statement is true?

• Only EM waves require a medium

• Only mechanical waves require a medium

• Both E and mechanical waves require a medium

• Only sound waves require a medium

Which wave would have the highest frequency?

• Green wave

• Blue wave

Which statement is true about sound waves?

• They travel fastest in solids.

• They travel slowest in solids

• They travel fastest in gases

• They always travel the same speed in all mediums

As the amplitude of the wave increases the energy of the wave __________

• increases

• decreases

• remains the same

Why are blue laser lights more dangerous to the human eye than red lights?

• Red light has a longer wave-length and therefore higher energy than blue light

• Red light has a shorter-wavelength, and thereof higher energy than blue light

• Blue light has a longer wave-length, and therefor higher energy than red light

• Blue light has a shorter wave-length and therefore higher energy than red light

Red color wave lengths have the shortest wavelengths and ___________ energy of all the visible light

• highest

• lowest

• most unstable
