An object is placed at a distance of 1.33 metres from a convex lens that has a focal length of 40 millimetres.

a) Where would you look (distance and apparent location from the lens) for a focused image to appear?

b) What orientation would the image appear: right-side-up or upside-down?

c) Determine the magnification of the image. Does your value confirm the answer in part b)?

d) If the object’s distance from the lens was shortened to 1.33 centimetres, how would the focused image change, including the magnification?

A concave lens has a focal length of magnitude 10 cm. It is placed a distance of 25 cm from a concave mirror with a focal length of magnitude 15 cm. An object is set a distance of 22 cm in front of the lens. The observer is at the same location as the object, so the light from the object goes through the lens, reflects off the mirror, and comes back through the lens to the observer. Draw the...

A small object is placed to the left of a convex lens and on its optical axis. The object is 30 cm from the lens, which has a focal length of 49 cm. If the object is moved to a position 57 cm away, what will the image position be? (A positive value for p, or position, means the image is on the right side of the lens.) p = ? cm Describe the nature of this new image. (Select...
