Reflection & Mirrors
This type of mirror surface results in a "sharp" image.
What is a smooth surface?
This term describes light bending as it passes from air into glass
Refraction
A purple neon sign emits light with these specific wavelengths.
What are purple wavelengths?
The name of the line drawn perpendicular ($90^{\circ}$) to a surface where light strikes.
What is the normal?
True or False: Reflection is the reason you can see your image in a mirror.
What is True?
This statement about convex mirrors is false when compared to flat mirrors.
What is "the image would appear the same"
A convex lens is also known by this "converging" or "diverging" name.
What is a converging lens
In a room with only red light, a green shirt would appear to be this color.
What is black?
This is the name for the light ray that is bouncing off a surface.
What is the reflected ray?
This is what happens to light when it hits a surface and is neither reflected nor passed through, often turning into heat.
What is absorption?
When you look in a flat mirror, the image you see is the same size as this.
What is the object?
Light bends specifically when it enters a new medium at this.
What is an angle?
This happens to most colors of light when they hit a purple object, except for purple itself.
What is absorption?
This is the name for the incoming light ray before it hits a surface.
What is the incident ray?
While reflection involves light bouncing off a surface, this process involves light traveling through a material and changing direction.
What is refraction?
This is the reason a person can see an image in a mirror.
What are reflected rays?
Cells in our eyes that see in dim conditions? Cells in our eyes that see color?
Dim conditions = rod cells
Color = cone cells
A banana looks yellow because it absorbs yellow light. True or False?
False, it reflects yellow light and absorbs all the other colors.
Blackout curtains are designed to keep light out. What kind of material is used to make them? (Hint: looking for a vocabulary word not fabric material)

Describe the shape of a concave mirror vs. convex mirror.
Concave mirror is thicker on the edges and convex is thicker in the middle
In a room with blue lights, my yellow t-shirt would appear as the color _____?
Black
The point where light rays converge to a point is called the ____________________ point.
Focal point
Why does black paint appear black?
Black paint appears black because it absorbs most or all wavelengths of visible light and reflects very little, so almost no light reaches your eyes.
