2 cards from this section. Quick, good the night before a test.
Calculate the image distance for an object placed 30 cm from a convex lens with a focal length of 15 cm.
Use 1/f = 1/v - 1/u.
What is the nature of the image formed by a concave mirror when the object is between F and P?
Think about the conventions of image types and positions.
What type of image does a convex lens produce when the object is far away?
Consider the lens properties based on object distance.
True or False: The angle of incidence at which total internal reflection occurs is less than the critical angle.
Remember the definition of critical angle!
A beam of light strikes the boundary of glass and water at given angles. Determine the angle of refraction when crossing each boundary.
Use ratios of sin for the angle relations.
Explain in detail how to find the effective focal length when two lenses are placed in contact.
Remember the distances and signs in the lens equation!
