Properties of Light and Optics

Explain the law of reflection of light.

• Reflection of light occurs at different speeds depending on the surface

• The law of reflection states that light bends at an angle

• The law of reflection of light states that the angle of incidence is equal to the angle of reflection.

• The angle of reflection is always greater than the angle of incidence

Choose the correct statement about how the mirrors reflect light.

• Plane mirrors reflect light by bouncing it off a flat surface, while concave mirrors reflect light towards a focal point.

• Plane mirrors reflect light by bending it, while concave mirrors reflect light away from a focal point.

• Convex mirrors reflect light by bending it, while concave mirrors reflect light towards a focal point.

• Plane mirrors reflect light by absorbing it, while concave mirrors reflect light away from a focal point.

What are the two main types of lenses?

• Solid and liquid lenses

• Convex and concave lenses

• Transparent and opaque lenses

• Flat and curved lenses

How does a prism work in optics?

• A prism works in optics by emitting light rather than separating colors.

• A prism works in optics by absorbing light and creating darkness.

• A prism works in optics by reflecting light instead of refracting it.

• A prism works in optics by refracting light and separating different colors to create a spectrum.

Differentiate between virtual and real mirrors with examples.

• Virtual mirrors are transparent.

• Virtual mirrors are digital representations, while real mirrors are physical objects that reflect light.

• Virtual mirrors are physical objects that reflect light.

• Real mirrors are digital representations.

What happens to light when it passes through a concave lens?

• It diverges or spreads out

• It reflects back

• It remains unchanged

• It converges or focuses

Describe the formation of an image in a convex mirror.

• The image formed in a convex mirror is real, inverted, and enlarged in size.

• The image formed in a convex mirror is virtual, upright, and diminished in size.

• The image formed in a convex mirror is real, upright, and enlarged in size.

• The image formed in a convex mirror is virtual, inverted, and enlarged in size.

How does light behave when it strikes a flat mirror?

• Light reflects off a flat mirror at the same angle it hits the mirror.

• Light absorbs into a flat mirror

• Light refracts when it strikes a flat mirror

• Light scatters in all directions when it strikes a flat mirror

What is the difference between refraction and reflection of light?

• Refraction involves the bending of light, while reflection involves the bouncing back of light.

• Refraction involves the absorption of light, while reflection involves the emission of light.

• Refraction involves the scattering of light, while reflection involves the absorption of light.

• Refraction involves the reflection of light, while reflection involves the bending of light.

How does a magnifying glass work in optics?

• A magnifying glass works by reflecting light to create a focused image.

• A magnifying glass works by absorbing light to enhance visibility.

• A magnifying glass works by refracting light to magnify objects.

• A magnifying glass works by scattering light to enlarge images.
