Physics Waves Quiz

The diagram shows two waves traveling in the same medium for the same length of time. The two waves have different

• amplitudes

• frequencies

• speeds

• wavelengths

A periodic wave travels through a rope, as shown in the diagram. As the wave travels, what is transferred between points A and B?

• mass, only

• energy, only

• both mass and energy

• neither mass nor energy

As shown in the accompanying diagram, a transverse wave is moving with velocity v along a rope. In which direction will segment X move as the wave passes through it?

• down, only

• up, only

• down, then up, then down

• up, then down, then up

An electric bell connected to a battery is sealed inside a large jar. What happens as the air is removed from the jar?

• The electric circuit stops working because electromagnetic radiation can not travel through a vacuum.

• The bell's pitch decreases because the frequency of the sound waves is lower in a vacuum than in air.

• The bell's loudness increases because of decreased air resistance.

• The bell's loudness decreases because sound waves can not travel through a vacuum.

A television remote control is used to direct pulses of electromagnetic radiation to a receiver on a television. This communication from the remote control to the television illustrates that electromagnetic radiation

• is a longitudinal wave

• possesses energy inversely proportional to its frequency

• diffracts and accelerates in air

• transfers energy without transferring mass

A student generates water waves in a pool of water. In order to increase the energy carried by the waves, the student should generate waves with a

• greater amplitude

• higher frequency

• greater wavelength

• longer period

The diagram below shows a tuning fork vibrating in air. The dots represent air molecules as the sound wave moves toward the right. Which diagram best represents the direction of motion of the air molecules?

• Circular motion

• Horizontal motion

• Vertical motion

• Linear motion
