Answer 1

Answer:

sorry

Step-by-step explanation:

2) Both A and R are true but R is not the correct

Answer 2

Answer:

(4) A is false but R is true

We know that

Intensity is the brightness of the image we obtained. And it depends on the diameter of the aperture.

We know that

Intensity is directly proportional to the area

But area = π r^2

And r =d/2

So area =πd^2/4

So now intensity is directly proportional to d^2

Which is the diameter of the aperture

Therefore the intensity of the image formed by smaller mirror will be less

Therefore the intensity of the image formed by smaller mirror will be lessHence assertion is false but reason is correct.
