How would you describe an electromagnetic wave?
A longitudinal wave that has two parts, one electrical and the other magnetic, that needs a medium to travel.
A transverse wave that has two parts, one electrical and the other magnetic, that does not need a medium to travel.
Only a longitudinal wave that does not need a medium to travel.
Only a transverse wave that needs a medium to travel.
How does light travel in a vacuum?
It travels in various speeds depending on frequency and wavelength.
It cannot travel in a vacuum.
It travels at the same speed no matter the frequency or wavelength,
It travels slower than when travelling through a vacuum.
How does the medium affect speed of light?
Gas is the fastest, liquid is slower, and solid is the slowest.
Solid is the fastest, liquid is slower, and gas is the slowest.
Gas is the fastest, solid is slower, and liquid is the slowest.
Light is composed of tiny particles called___________________.
Plasma
Protons
Neutrons
Photons
What is the relationship between frequency and photon energy?
There is no relationship between frequency and photon energy.
The greater the frequency, the greater the photon energy.
The greater the frequency, the less the photon energy.
Reflection in an electromagnetic wave is caused by _____________________.
When light strikes a surface and bounce off.
When light strikes only a rough surface and bounce off.
When light strikes only a smooth surface and bounce off.
The bending of light waves traveling from one medium to another.
Diffused reflection happens when__________________________.
The surface is smooth as glass.
light bends when entering a different medium.
The surface is rough and/or uneven.
The Law of Reflection states:
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,
The angle of incidence and the angle of reflection must equal each other.
What does A and B in the illustration show pertaining to the law of reflection?
A - Angle of reflection
B - incident angle
A - Incident Angle
B - Angle of Reflection
A - Incident Ray
B - Angle of Reflection
A - Reflected Ray
B - Angle of Reflection

Refraction of an electromagnetic wave is caused by _____________________.
When light strikes a surface and bounce off.
When light strikes only a rough surface and bounce off.
When light strikes only a smooth surface and bounce off.
The bending of light waves traveling from one medium to another.
Dispersion of an electromagnetic wave is caused by__________________________.
When light strikes only a smooth surface and bounce off.
The bending of light waves traveling from one medium to another.
The separation of visible light into individual colors.
The bending of waves around barriers.
What does diffraction of an electromagnetic wave mean?
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.
The bending of waves around barriers.
What we are able to see depends on:
Only the amount of light of an object.
The amount of light and the color of the objects as they reflect or absorb light.
The color of the object.

When light is scattered
Reflection
Refraction
Absorption
Diffusion
Mark the correct description for Absorption.
The Light scattered.
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.
When light waves enter a new medium at an angle, their speed changes.
Mark the correct description for Refraction.
The Light scattered.
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.
When light waves enter a new medium at an angle, their speed changes.
Mark the correct description for Diffusion.
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.
When parallel rays of light hit a bumpy surface.
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 all wavelengths of visible light at once in equal proportions.
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 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 toward the line of "normal"
The refracted light will bend away from the line of "normal"
