Light Reflection in a Plane Mirror

The video tutorial explores the concept of reflection, focusing on how it occurs in plane mirrors. It explains the difference between light sources and objects that reflect light, and delves into the formation of virtual and real images. The tutorial highlights the characteristics of images in plane mirrors, such as orientation, size, and distance. It also covers lateral inversion and its practical implications, like in ambulance signage. Finally, the video discusses symmetry in relation to mirror images, providing examples with letters and their axes of symmetry.

What is a light source in the context of reflection?

• An object that refracts light

• An object that reflects light

• An object that emits its own light

• An object that absorbs light

How is a virtual image formed in a mirror?

• By the refraction of light rays

• By the absorption of light rays

• By the assumed meeting of light rays

• By the actual meeting of light rays

Which type of mirror forms a real image?

• Plane mirror

• Convex mirror

• Cylindrical mirror

• Concave mirror

What is the orientation of an image in a plane mirror compared to the object?

• Erect

• Inverted

• Smaller

• Larger

What is lateral inversion?

• The reversal of top and bottom

• The reversal of front and back

• The reversal of left and right

• The reversal of size

Which letter remains unaffected by lateral inversion?

• B

• A

• C

• D

Which of the following letters has both vertical and horizontal axes of symmetry?

• A

• B

• H

• C
