Wave Behaviors

Front

What is refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another, causing a change in speed.

Front

What happens to light waves when they enter water from air?

Back

Light waves slow down and bend towards the normal line.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What color do we perceive an object that absorbs all visible light?

Back

Black.

Front

What is reflection?

Back

Reflection is the bouncing back of light waves when they hit a surface.

Front

What is transmission in the context of light waves?

Back

Transmission is the passing of light waves through a medium without being absorbed.

Front

What is absorption in terms of light waves?

Back

Absorption is when light waves are taken in by a material, converting light energy into other forms of energy.

Front

What is the normal line in optics?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence where light waves strike.

Front

What is the difference between transparent, translucent, and opaque materials?

Back

Transparent materials allow light to pass through clearly, translucent materials allow some light to pass but scatter it, and opaque materials do not allow light to pass through.

Front

What is the principle of superposition in wave behavior?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.
