Formation of Images

What is reflection of light?

• Reflection of light is the process where light disappears upon hitting a surface.

• Reflection of light is the process where light bounces off a surface.

• Reflection of light is the process where light is absorbed by a surface.

• Reflection of light is the process where light passes through a surface.

Explain refraction of light.

• Refraction of light is the splitting of light into its component colors.

• Refraction of light is the bending of light as it passes from one medium to another due to a change in its speed.

• Refraction of light is the reflection of light off a surface.

• Refraction of light is the absorption of light by a medium.

Describe how real images are formed.

• Real images are formed when light rays pass through a lens without converging.

• Real images are formed when light rays diverge at a specific point after passing through a lens.

• Real images are formed when light rays reflect off a lens.

• Real images are formed when light rays converge at a specific point after passing through a lens.

How are virtual images formed?

• Virtual images are formed when light rays pass through the mirror or lens without any deviation.

• Virtual images are formed when light rays converge at a point behind the mirror or lens.

• Virtual images are formed when light rays appear to converge in front of the mirror or lens.

• Virtual images are formed when light rays appear to diverge from a point behind the mirror or lens.

What happens when light rays pass through a concave mirror?

• Light rays converge or diverge based on the object's position relative to the focal point, creating real or virtual images.

• Light rays reflect back in the same direction

• Light rays pass through without any change

• Light rays disperse in all directions

Define the term 'focal length' of a lens.

• Focal length is the measure of the lens's weight.

• The focal length of a lens is the distance between the lens and the object being focused on.

• Focal length refers to the width of the lens aperture.

• The focal length of a lens is the distance between the lens's optical center and the focal point.

Explain the difference between a concave and convex lens.

• A concave lens converges light rays, while a convex lens diverges light rays.

• A concave lens focuses light rays, while a convex lens disperses light rays.

• A concave lens diverges light rays, while a convex lens converges light rays.

• A concave lens bends light rays towards a focal point, while a convex lens bends light rays away from a focal point.

How does a convex mirror form an image?

• By reflecting light rays converging from the object to create a real, inverted, and magnified image.

• By reflecting light rays diverging from the object to create a virtual, upright, and diminished image.

• By refracting light rays diverging from the object to create a virtual, upright, and magnified image.

• By absorbing light rays from the object and creating no image.

How does a concave lens differ from a convex lens in terms of light refraction?

• A concave lens refracts light towards a focal point, while a convex lens refracts light away from a focal point.

• A concave lens disperses light rays, while a convex lens converges light rays.

• A concave lens focuses light rays, while a convex lens diverges light rays.

• A concave lens bends light rays away from a focal point, while a convex lens bends light rays towards a focal point.
