Question

A 10 cm tall object is placed 30 cm away from a concave lens that has a focal length of 6.0
cm.
1. Determine the distance separating the lens from the image.
2. Determine the image size.

Answer 1

Answer:

Distance of image =5cm

Explanation:

We will use the formula 1/f=1/v-1/u and put the values of f and u to find v. Image size =5 cm by the formula h/10 = v/u where h = height, 10cm = current height , v = distance  of image formed and u is distance of object placed.

I'm not sure if this is correct so wait for other answers, if this is incorrect then please report this otherwise have fun.
