Chapter 7 Geometrical Optics (C1 & C2)

To determine the characteristics of image formed we need to a draw ray diagram that uses

• at least 2 rays that overlap each other

• at least 3 rays out of 4 rays

• plane mirror or lens

• rays that passes through biconcave or biconvex mirror

The distance from center of mirror, C to the pole of mirror is given as

• 2f

• v

• u

• 2R

An image that is formed at the back of the mirror is said to be

• real image

• virtual image

• inverted image

• magnified image

An image is formed upside down in front of mirror and seems bigger by 2 times from the actual size. What might be the type of mirror uses?

• concave mirror

• convex mirror

• plane mirror

• concave lens

Which statement is true about convex mirror?

• image formed is virtual and diminished

• have a positive value of focal length

• image formed is real and diminished

• image formed is real and magnified

What is the formula for magnification?

• -v / u

• -h_i / h_o

• h_i / h_o

• v/u

State the characteristic of image foremd

• real, inverted and diminished

• virtual, upright and diminished

• virtual, upright and magnified

• real, upright and diminished

An image formed when the light rays pass through the image location, and could appear on paper or film placed at the that location is referred to as a

• real image.
• virtual image.
• source image.
• original image.

A spherical mirror on which reflection takes place on the inner surface of the sphere is referred to as a

• convex mirror.
• concave mirror.
• convex lens.
• concave lens.

An object is positioned between a concave mirror's center of curvature and its focal point. The image produced by the mirror is located

• out past the center of curvature.
• at the center of curvature.
• between the center of curvature and the focal point.
• at the focal point.
