Question 14
14.
When a light bulb in a lamp receives electrical energy, it will produce light. The term that that is used to indicate that the light source produces light is...
Question 15
15.
This illustration demonstrates a type of reflection referred to as ...
Question 16
16.
Reflection is the process in which light strikes a surface and bounces off that surface. The reflected ray will bounce back directly to the light source if it is lined up with the ...
Question 17
17.
In stating the law of reflection, the angle of incidence equals the angle of reflection, it is necessary to understand that this is a law because...
Question 18
18.
When you attempt to focus an image on a screen, using a concave mirror, but cannot, yet, you can see an image when you are looking into the same concave mirror, the image is called a ...
Question 19
19.
When parallel rays of light hit the surface of this type of mirror, they are reflected back to a focal point in front of the mirror. The type of mirror that does this is called an...
Question 20
20.
Cosmetic mirrors, flashlights, reflecting telescopes, and the headlights in a car are all examples of practical applications for these type mirrors...
Question 21
21.
If an object is placed between the focal point in a concave mirror and the mirror itself, the image will appear...
Question 22
22.
Refraction is the bending of light when it travels from one medium to another. What direction does the light bend when it travels from a medium of greater density to one of lesser density?
Question 23
23.
Mirages cause an illusion of a watery surface. This illusion is actually...
Question 24
24.
During refraction, when the angle of incidence is doubled, the angle of refraction is ...
Question 25
25.
When light is passing through a lens, the light is bent, causing the rays of light to diverge. The type of lens is a...
Question 26
26.
When light rays pass through a convex lens, the image that is formed is...
Question 27
27.
The arrows in (a) and (b) - identified in the illustration above - indicate the...
Question 28
28.
As frequency increases, this will happen to the wavelength...
Question 29
29.
White light is refracted through a device that breaks it up into all the visible colors that make up white light. The device that does this is called a...
Question 30
30.
The only type of radiation which can penetrate solid material and concrete walls is ...
Question 31
31.
Radar is an acronym for radio detection and ranging. These devices send out waves, which bounce off objects and return (obeying the law of reflection). Older radar devices use radio waves, whereas modern radar devices use...
Question 32
32.
Phosphorescence is slightly different from fluorescence. In phosphorescence, the energy used to produce the light is absorbed by the material and given off later. These types of materials...
Question 33
33.
Incandescent light bulbs produce 95% heat and only 5% visible light. Fluorescent light bulbs are much more efficient because they make 80% heat and ...
