Question

Assertion: Linear magnification of a mirror has no unit.
Reason: The ratio of height of the image to the height of the object is the linear magnification producby mirror.

a) Both A and R are true, and R is correct explanation of the assertion.
b) Both A and R are true, but R is not the correct explanation of the assertion.
c) A is true, but R is false.
d) A is false, but R is true. ​

Answer 1

Answer:

Both A and R are true and R is correct explanation of the assertion.

Explanation:

• Linear magnification : The ratio of height of the image to the height of the object is known as linear magnification. Since it is a ratio, it is unitless and is represented in the form of  number. Its value can never be negative.

• It can also be represented in terms of image distance and the object distance from the pole. The ratio of image distance to the ratio of object distance is also called linear magnification.

So from the above explanation it is clear that both Assertion and reason are true and reason is the correct explanation of assertion.

Answer:

B is the correct hopefully helps for you
