Q. 1

# A person looks at different trees in an open space with the following details. Arrange the trees in decreasing order of their apparent sizes.

Answer :

Let be the angle formed by the eyes while looking at tree, then,

For trees, A,B,C and D, the value of angle becomes-

When becomes more, the apparent sizes also becomes large.

Hence the sequence *A*, *B*, *C*, *D*

A normal eye has retina 2 cm behind the eye-lens when the eye is (A) fully relaxed, (B) most strained?

HC Verma - Concepts of Physics Part 1A professor read a greeting card received on his 50th birthday with + 25 D glasses keeping the card 25 cm away. Ten years later, he reads his farewell letter with the same glasses but he has to keep the letter 50 cm away. What power of lens should he now use?

HC Verma - Concepts of Physics Part 1A person wears glasses of power − 25 D. Is the person farsighted or nearsighted? What is the far point of the person without the glasses?

HC Verma - Concepts of Physics Part 1An astronomical telescope is to be designed to have a magnifying power of 50 in normal

adjustment. If the length of the tube is 102 cm, find the powers of the objective and the eyepiece.

HC Verma - Concepts of Physics Part 1

The separation between the objective and the eyepiece of a compound microscope can be adjusted between 98 cm to 118 cm. If the focal lengths of the objective and the eyepiece are 10 cm and 6 cm respectively, find the range of the magnifying power if the image is always needed at 24 cm from the eye.
