Is Visible Light Dangerous?
No, Visible light cannot harm you
Yes, visible light is highly radioactive and should be handled carefully. Visible light when in contact with human skin can cause aerial skin cancer.
No, this is because visible light isn't real
Yes, Visible light at high concentrations can cause burns, blindness, and indirect DNA damage but at low levels is harmless
Which of the following IS NOT a behavior that light waves can undergo when they reach a boundary between two media?
stopping at the edge of the boundary
reflection off of the boundary
transmission into the boundary
refraction through the boundary
Reflection is to bouncing as refraction is to:
bending.
breaking.
dissipating.
halting.
A concave mirror is shaped like the inner surface of a sphere. How do you think light rays will reflect off a concave mirror?
Reflected rays converge toward the center line of a concave mirror.
Reflected rays diverge away from the center line of a concave mirror.
Reflected rays reflect straight back at the angle that they came in.
Reflected rays are absorbed by a concave mirror.
The way that a surface reflects light depends on its texture. Rough surfaces such as cloth and wood tend to scatter light, reflecting it in many different directions. This type of reflection is called:
diffuse reflection.
specular reflection.
incident reflection.
distorted reflection.
