What is the focal length of a mirror if the object is known to be 2 m and the image position is 1.5 m - ANSWER-1/f = 1/do + 1/di -> 1/f = 1/2 + 1/1.5 -> 1/f = 1.16 -> f = 1/1.16 = 0.86m
An object with a height of 4 cm is at a position 6cm is front of a converging lens. The image inverts and is at a position 3 cm from the lens. The image height is... - ANSWER-m=di/do = 3/-6 = -.5 -> m=hi/ho -> -.5 = hi/4 -> hi = (-.5)(4) = -2cm
A light ray traveling through a material with an index refraction of 1.2 is incident on a material that has an index of refraction of 1.4. Compared to the incident angle, the refracted angle of the light ray is - ANSWER- smaller than the incident angle

Lens arrangement that will always result in images that are smaller than the original objects - ANSWER-any object placed at any do in front of the diverging lens
An object is at a position 6cm from the converging lens with a focal length of 3cm. Compared to the object height, the height of the image is
- ANSWER-same size
You placed an object in front of a lens and observe a real image. Which arrangement could produce that image? - ANSWER-A converging lens but only if the object is placed at do>f
An arrow is in front of a mirror (dot, upright arrow, lens) the resulting image can be best describes as - ANSWER-virtual and upright
When solving for and image distance, a resulting negative value for di indicates - ANSWER-virtual image
The focal length of a curved mirror depends on - ANSWER-the radius of the curvature of the mirror
