Question

Hello everyone, I want to ask a question, Please answer, Question:Why value of linear magnification in concave mirror is greater than 1,less than 1 or equal to 1

Answer 1

Answer:

Here is ur answer

Explanation:

Another point to be noted is that if the value of magnification is equal to 1, then the image formed is of the same size as that of object. If the value of magnification is more than 1, then the image formed is enlarged, and if the value of magnification is less than 1, then the image formed is diminished.

Answer 2

★ Answer :

As the object is always placed above the principal axis so the magnitude of h1 is always positive. But h2 can be positive or negative depending on whether the image formed is virtual or real. As the virtual image is always erect and above the principal axis therefore h2 will be positive. On the other hand, the real image is always inverted and formed below the principal axis so h2 will be negative. Thus magnification m will be positive when h2 is positive (i.e. image formed is virtual and erect) and m will be negative when h2 is negative (i.e. image formed is real and inverted). So, value of linear magnification in concave mirror is greater than 1,less than 1 or equal to 1.
