The Law of Reflection states:

The angle of incidence and the angle of reflection must equal each other.

The angle of reflection is 90 degrees to the angle of incidence.

The angle of incidence is 90 degrees to the angle of reflection.

The angle of incidence and the angle of reflection are parallel to each other,

What does A and B in the illustration show pertaining to the law of reflection?

A - Incident Ray B - Angle of Reflection

A - Angle of reflection B - incident angle

A - Incident Angle B - Angle of Reflection

A - Reflected Ray B - Angle of Reflection

Dispersion of an electromagnetic wave is caused by__________________________.

The separation of visible light into individual colors.

The bending of waves around barriers.

What does diffraction of an electromagnetic wave mean?

The bending of waves around barriers.

The angle of incidence is equal to the angle of reflection if the surface is smooth.

The greater the difference between the speed of light in two media, the more the light is bent as it passes at an angle from one medium to another.

When a wave strikes an object and bounces off.

What we are able to see depends on:

The amount of light and the color of the objects as they reflect or absorb light.

Only the amount of light of an object.

Mark the correct description for Absorption.

Light does not pass through or reflect from the material but remains in the material as energy.

Occurs when parallel rays of light hit a smooth surface.

Each ray obeys the law of reflection, but each ray hits the surface at a different angle.

When light waves enter a new medium at an angle, their speed changes.

Mark the correct description for Refraction.

When light waves enter a new medium at an angle, their speed changes.

Occurs when parallel rays of light hit a smooth surface.

Light does not pass through or reflect from the material but remains in the material as energy.

Each ray obeys the law of reflection, but each ray hits the surface at a different angle.

Mark the correct description for Diffusion.

When parallel rays of light hit a bumpy surface.

This law states the angle of reflection equals the angle of incidence.

All the rays are reflected at the same angle.

the change in speed causes them to bend or change direction.

A measure of how much a ray of light bends when it enters another material.

We see an object as white because:

Our eyes detect all wavelengths of visible light at once in equal proportions.

Our eyes detect only white light and all other color light is absorbed.

Our eyes detect all the wavelengths of visible light at once, but the white is stronger.

We see an object as black because:

Our eyes detect black because the object has absorbed almost all the light waves and reflect little light back to our eyes.

Our eyes detect all wavelengths of visible light at once in equal proportions.

Our eyes detect all the wavelengths of visible light at once, but the black is stronger.

Will the line of refraction bend toward or away the line of "normal"?

The refracted light will bend away from the line of "normal"

The refracted light will bend toward the line of "normal"

The refracted light will not bend and travel in a straight line

Will the refracted light bend toward or away the line of "normal"?

The refracted light will bend toward the line of "normal"

The refracted light will bend away from the line of "normal"

The refracted light will travel in a straight line
