Waves- Physical Science

A sound wave is produced in a metal cylinder by striking one end. Which of the following occurs as the wave travels along the cylinder?

• Its amplitude increases.

• Its frequency increases.

• It transfers matter.

• It transfers energy.

A radio station transmits to a receiving antenna. The radio wave sent is a

• Transverse Wave

• Longitudinal Wave

• Sound Wave

• Compression Wave

A stretched spring attached to two fixed points is compressed on one end and released as shown in the image. The resulting wave travels back and forth between the two fixed ends of the spring until it comes to a stop. This mechanical wave is an example of a

• Transverse Wave

• Longitudinal Wave

• Refracted Wave

• Reflection

Astronauts on the Moon would not be able to hear a landslide because

• the lunar dust deadens sounds.

• intense sunlight destroys sound waves.

• the magnetic field of the Moon is too weak to carry sound.

• air molecules on the Moon are too far apart to carry sound.

Sound waves cannot carry energy through

• water

• air

• space

• a mirror

Where does visible light fall on the electromagnetic spectrum?

• between x-rays and gamma rays

• between infrared and ultraviolet

• between microwaves and infrared

In a vacuum, radio waves, visible light waves, and x-rays all have the same

• wavelength

• speed

• frequency

Which of the following choices best explains why grass on a distant hillside appears green?

• Grass reflects all colors except green.

• Grass absorbs only green light from the sun.

• Grass reflects green light more than any other color.

• Your eyes absorb only green light.

The two waves in the images are traveling at the same speed. Which statement best describes the difference between the waves?

• Wave A has a higher frequency than wave B.

• Wave A has a lower frequency than wave B.

• Wave A has a higher amplitude than wave B.

• Wave A has a lower amplitude than wave B.

What happens to the path of a light ray as it passes from air into water at an angle?

• Its path widens

• Its path bends

• Its path becomes shorter

• Its path continues in a straight line
