Waves Unit Test Review

Two people each hold the end of a rope and create waves by moving their arms up and down. This wave is best classified as a transverse wave because ___________.

• both the rope particles and the wave are moving in the same direction

• the wave is moving up and down as the particles of the rope move horizontally.

• the wave is moving horizontally as the particles of the rope move up and down.

• the wave is moving in a parallel direction with the motion of the person's arms.

An old movie poster used a quote "In space, no one can hear you scream!" Why this is true or not true?

• The quote is incorrect, you can hear sound in outer space.

• Sound cannot be polarized. So, you cannot hear sound in space.

• Sound is an electromagnetic wave and needs no medium to travel through.

• Sound needs a medium for the wave to vibrate and there is nothing in space to vibrate.

Which of these are not mechanical waves and can be used to send a signal to satellites orbiting the earth?

• sound waves

• radio waves

• both sound waves and radio waves

• neither sound waves or radio waves

How are the energy of infrared, visible light and ultraviolet rays related? And why?

• Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is proportional to its wavelength.

• Infrared contains the most energy and ultraviolet contains the least energy. The energy of a wave is proportional to its wavelength.

• Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its wavelength.

• Infrared contains the most energy and ultraviolet contains the least energy. The energy of a wave is inversely proportional to its wavelength.

How do vibrations move in a longitudinal wave?

• Vibrations only move up.

• Vibrations do not move in a pattern.

• Vibrations move up and down.

• Vibrations move back and forth.
