Light and Sound Waves

As a wave moves through a medium, the particles of the medium move back and forth, parallel to the direction of motion of the wave as shown in the image. What kind of wave does the image show?

• electromagnetic transverse wave

• mechanical longitudinal wave

• electromagnetic longitudinal wave

• mechanical transverse wave

Which statement most completely defines a wave?

• A wave transfers matter through a medium or empty space without transporting energy.

• A wave transfers energy and matter from one point to another through a medium.

  
  

• A wave transfers energy and matter from one point to another through empty space.

• A wave transfers energy through a medium or empty space without transporting matter.

Solar panels are often installed on rooftops of homes and buildings as well as in open fields. What is the main purpose of installing solar panels?

• to capture and convert wind energy into energy in the form of light waves

• to capture and convert electrical energy into energy in the form of light waves

• to capture and convert energy from light waves into energy in the form of electricity

• to capture and convert energy from light waves into energy in the form of sound waves

In what way are sound waves similar to light waves?

• Sound waves and light waves create energy by vibrating particles.

• Sound waves and light waves travel the fastest through empty space.

• Sound waves and light waves absorb particles when they pass through solid matter.

• Sound waves and light waves transmit energy without transporting matter.
