PHYS 1808: Physics 2 - Lecture 6 Flashcards

Flashcards covering concepts from Physics 2 Lecture 6, including image formation in mirrors.

When an observer looks at an object in a swimming pool, will the object appear to be at a depth that is less than, greater than, or the same as the actual depth of the pool?

Less than the depth of the pool.

In a curved mirror diagram, what is the line indicated referred to as?

Optic axis

what do s, s’, and R represent?

s = object distance, s’ = image distance, R = radius of curvature

What are the two properties of the focal point (F) of a spherical mirror?

Any incoming ray parallel to the optic axis is reflected through the focal point, and any incoming ray that passes through the focal point is reflected parallel to the optic axis.

How is lateral magnification defined?

y’/y, where y’ is the image height and y is the object height.

What are the three principle rays used in ray diagrams for concave mirrors?

In parallel out through the focus, In through the center of curvature, back along the same path, In through the focus out parallel

What are the three principle rays used in ray diagrams for convex mirrors?

In parallel out through the focus, In through the center of curvature, back along the same path, In through the focus out parallel
