Consider an astronomical telescope with a 48 centimeter focal-length objective lens and a 10 centimeter focal-length eyepiece. Approximately how many centimeters apart should the lenses be placed

D = 58 cm

Explanation:

Given that,

Focal length of the objective lens,

Focal length of the eye piece,

We need to find how many cm apart should the lenses be placed. Let d be the distance between lenses. It is equal to the sum of focal lengths of objective lens and eye-piece

D = 48 cm + 10 cm

= 58 cm

Hence, the object is placed at a distance of 58 cm.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
