Honors Optics

The distance between the focal point and the mirror is

• raduis
• diameter
• focal point
• focal length

All rays that are parallel to the principle axis in a concave mirror reflects 

• Towards the focal point
• Away from the focal point
• Towards the center of curvature
• Away from the center of curvature

In a concave mirror, if an incident ray passes through F and hits the mirror then it will reflect

• Towards C
• Towards F
• Parallel
• Away from the mirror

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.

What type of image does this lens form?

• Virtual image
• Real Image
• No Image

Compared to the object in front the lens, its image is.....

• inverted and smaller
• inverted and larger
• not inverted and smaller
• not inverted and larger

In the formula m = hi/ho, the variable "m" refers to ___.

• the height of the image
• the height of the object
• the focal point
• how reduced or enlarged the image is compared to the object

A 25.0 m object is placed 30.0 m from a convex lens, which has a focal length of 5.0 m. What is the distance of the image?

• 6 m

• 7 m

• 8 m

• 9 m

Speed of light in a vacuum is

• represented by the symbol "c"
• 3.00 X10⁸ m/s 
• both answers are correct

What is the index of refraction of a refractive liquid if the angle of incidence in the air is 35 degrees and the angle of refraction is 14 degrees?

• 1.33
• 2.21
• 2.37
• 1.72
