Mirrors | MCQs

Explanation

Explanation

• A plane mirror produces a virtual image, meaning it's not a real image that can be projected onto a screen.
• The image is also upright, meaning it's not inverted or flipped.

Explanation

• Dentist mirrors are typically concave mirrors.

• Rear-view mirrors
• Blind Corner mirrors 
• Security mirrors

Explanation

• Security mirrors are typically convex mirrors.

The examples of concave mirrors:

• Cosmetic mirrors (makeup mirrors)
• Dentist mirrors
• Car headlight mirrors

Explanation

When an object is placed far away from a concave mirror, its image will be:

• Real (a projected image that can be seen on a screen)
• Inverted (upside down)
• Smaller in size than the object (reduced)

Explanation

When an object is placed very close to a concave mirror, its image will be:

• Virtual (not a real image that can be projected onto a screen)
• Upright (not inverted)
• Larger in size than the object (magnified)

Explanation

• A mirror with a reflecting surface that bulges outwards, like the back side of a spoon, is called a Convex Mirror.
• This type of mirror is used in applications such as security mirrors, rear-view mirrors, and surveillance mirrors, as it provides a wider field of view.

Explanation

• A Concave Mirror has a curved reflecting surface that bulges inward, like the front side of a spoon.
• This type of mirror is used in telescopes, solar concentrators, and other applications where light needs to be focused.

Explanation

• A kaleidoscope contains several mirrors placed at an angle to each other, usually 60 degrees.
• This allows multiple reflections to be created of the objects inside the kaleidoscope.

Explanation

• A Periscope uses two plane mirrors placed at a 45° angle to each other.
• It allowing the user to see objects that are not in their direct line of sight.
• This is commonly used in submarines, tanks, and other applications where visibility is limited.
