A converging lens has a focal length of 20 cm. An object 1 cm tall is placed 10 cm from the center of the lens. What is the height of the image? (note: solve for the image distance first)

2 cm

Explanation:

Given , for a converging lens

Focal length :

Height of object :

Object distabce from lens :

Using lens formula: , we get

, where v = image distance from the lens.

On solving aboive equation , we get

Formula of Magnification : , where h' is the height of image.

Put value of u, v and h in it , we get

Hence, the height of the image is 2 cm.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
