Question

write difference
between convex and
Concave mirror​

Answer 1

Answer:

the inner side of the spherical mirror is reflecting, it is called a concave mirror. If the outer side of the spherical mirror is reflecting, it is called a convex mirror. Concave mirrors can form inverted and real images and also virtual and erect images.

Explanation:

गोलाकार दर्पण का आंतरिक पक्ष प्रतिबिंबित होता है, इसे अवतल दर्पण कहा जाता है। यदि गोलाकार दर्पण का बाहरी भाग प्रतिबिंबित हो रहा है, तो इसे उत्तल दर्पण कहा जाता है। अवतल दर्पण उल्टे और वास्तविक चित्र बना सकते हैं और आभासी और स्तंभित चित्र भी।

Answer 2

Differences between convex and concave mirror:

Convex mirror:

1. The reflecting surface is curved outward.

2. After reflection from the mirror the light rays diverge.

3. The image formed due to convex mirror is always virtual and diminished.

4. It is used as rear view mirror.

Concave mirror:

1. The reflecting surface curved inward.

2. After reflection from the mirror the light rays converge.

3. The image formed due to concave mirror is generally real and either diminished or magnified. But when an object placed between vertex and focus it is virtual.

4. It is used in car headlights.
