Question

दर्पण के सामने किसी भी दूरी पर स्थित वस्तु का प्रतिबिम्ब सीधा प्रतीत होता है तो वह दर्पण है

Answer 1

Answer:

Plane mirror and convex mirror always form virtual and erect image of all real objects in front of mirror

Explanation:

If the image of an object in front of mirror is always erect image then this type of mirror is always

1) Plane Mirror

2) Convex mirror

Plane mirror always form virtual and erect image of all objects. The size of image is equal to size of object always

While in convex mirror we have

$\frac{1}{d_i} + \frac{1}{d_o} = \frac{1}{f}$

here focal length of the mirror is positive while object distance with respect to mirror is negative

So image distance is always positive and hence we got virtual and erect image of object in front of convex mirror
