Question

Give the scientific reason for the following.
a) The focal length of the eyepiece of a compound microscope is larger.
b) A telescope of a binocular has two total internal reflecting prisms.

Answer 1

1. The focal length of the eyepiece of a compound microscope is larger so that the final image formed is a highly magnified image.
2. A telescope of a binocular has two total internal reflecting prisms which help in inverting the image formed by the objective as a result the final image is erect and magnified.
