Waves 2.0

How does the motion of a sound wave differ from the motion of a light wave?

A sound wave travels back and forth It's created by a squeezed portions that move through space. A light wave travels in an up and down motion.

is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough .

Amplitude

Sound waves travel faster than light waves.

False

How is a sound wave similar to a light wave?

Light and sound waves transmit energy, can reflect off of objects and be absorbed.

How are humans able to perceive light waves?

Light waves are detected by eyes and ears, and then processed by the brain.

Sound waves are considered "pressure waves" meaning particles push one another in the medium through which they're transferring.

True

When a wave hits an object, energy from the wave is both absorbed and reflected off the object.

True

You will see lightning before you can hear thunder.

True

How does the height of a wave relate to its energy?

Waves with large height are brighter or louder.

A wave can be defined as

a disturbance that travels through a medium, transmitting energy from one point to another.

Microwave, Light and Sound are

Waves can be measured by examining the
