Reflection of Light Quiz

What is the law of reflection?

• The angle of incidence is equal to the angle of reflection.

• The angle of reflection is less than the angle of incidence.

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

• The angle of reflection is perpendicular to the angle of incidence.

Explain regular reflection with an example.

• Regular reflection occurs when light reflects off a rough surface

• When light reflects off a mirror, it follows the law of reflection where the angle of incidence is equal to the angle of reflection.

• Regular reflection is when light passes through a transparent object

• When light reflects off a mirror, it creates a rainbow effect

What is the difference between regular reflection and diffuse reflection?

• Regular reflection only occurs with opaque surfaces, while diffuse reflection only occurs with transparent surfaces.

• Regular reflection occurs when light rays are reflected in various directions, while diffuse reflection occurs when light rays are reflected in a parallel manner.

• Regular reflection results in a clear image, while diffuse reflection results in a blurry image.

• Regular reflection occurs when light rays are reflected in a parallel manner, while diffuse reflection occurs when light rays are reflected in various directions.

How does a plane mirror reflect light?

• It refracts the light instead of reflecting it

• It absorbs the light completely

• It reflects light at the same angle as it hits the mirror.

• It reflects light at a 90-degree angle

What is the difference between a plane mirror and a concave mirror?

• Plane mirrors produce real images, while concave mirrors produce virtual images.

• Plane mirrors are used in telescopes, while concave mirrors are used in bathrooms.

• Plane mirrors reflect light in a straight line, while concave mirrors reflect light in a curved path.

• Plane mirrors produce virtual images, while concave mirrors can produce both real and virtual images.

State the angle of incidence and the angle of reflection in the law of reflection.

• The angle of deflection and the angle of transmission

• The angle of incidence and the angle of refraction

• The angle of incidence and the angle of reflection

• The angle of reflection and the angle of absorption

Give an example of diffuse reflection in everyday life.

• A mirror in a dark room

• A sidewalk on a sunny day

• A polished metal surface in direct sunlight

• A glass window on a cloudy day

Explain how a concave mirror reflects light.

• The light rays are reflected and diverge away from a focal point.

• The light rays are reflected and converge towards a focal point.

• The light rays are reflected and spread out in all directions.

• The mirror absorbs the light and does not reflect it at all.

Describe how light is reflected from a concave mirror when the object is placed beyond the center of curvature.

• Real and upright image at the focus

• Virtual and upright image at the center of curvature

• No image is formed

• Real and inverted image between the center of curvature and the focus

Explain the concept of total internal reflection.

• It occurs when light passes from a medium with a higher refractive index to a medium with a lower refractive index.

• It occurs when light passes from a medium with a lower refractive index to a medium with a higher refractive index.

• It occurs when light passes from a medium with a higher refractive index to a medium with the same refractive index.

• It occurs when light passes from a medium with a lower refractive index to a medium with the same refractive index.
