Flashcards about Geometric Optics

For a concave converging mirror, if an object is located at point A, the image formed is…

real and inverted

What kind of images can diverging lenses form?

Virtual images

What is the angle of reflection if a light ray strikes a plane mirror at 30 degrees?

60°

What kind of images can converging lenses form?

Either converging or diverging lenses

What kind of images can a diverging (concave) lens form?

virtual and upright

What kind of images can a convex (diverging) mirror produce?

virtual images, only

What kind of images can be projected onto a screen?

real images, only

What optical devices in air can both form real images?

concave mirror and convex lens

Compared to the image when the object is at point O, the image when the object is at point B will be…

nearer the lens

Moving the object from point O to point D will cause its image to…

change from inverted to upright

The diagram below shows a lens with an object located at position A . As the object is moved from position A to position B, the image formed by the lens will be…

inverted and increasing in size

What is the angle of reflection for a light ray reflecting from a plane mirror at 70 degrees?

70°
