Waves Test 1

Front

Interference of light is evidence that ___________.

Back

light is a wave phenomenon.

Front

Heat radiation, also known as ________________ cannot be seen by your eyes but can be felt by your skin.

Back

infrared waves.

Front

What type of wave is this?

Back

Longitudinal.

Front

What type of electromagnetic radiation has the highest energy?

Back

Gamma rays.

Front

These two waves will ________ interfere and result in a _________ amplitude.

Back

destructively, decreased.

Front

Define a transverse wave.

Back

A wave in which the particle displacement is perpendicular to the direction of wave propagation.

Front

Define a longitudinal wave.

Back

A wave in which the particle displacement is parallel to the direction of wave propagation.

Front

What is the principle of superposition in wave interference?

Back

When two or more waves overlap, the resultant displacement is the sum of the individual displacements.

Front

What is constructive interference?

Back

When two waves meet in phase, resulting in a wave of greater amplitude.

Front

What is destructive interference?

Back

When two waves meet out of phase, resulting in a wave of lesser amplitude.
