Light and Reflection

What is the law of reflection?

• The law of reflection only applies to curved surfaces.

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

• The law of reflection states that light bends when it hits a surface.

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

Explain the difference between regular and diffuse reflection.

• Regular reflection involves absorption of light rays, while diffuse reflection involves reflection of light rays in various directions.

• Regular reflection involves parallel reflection of light rays, while diffuse reflection involves reflection of light rays in various directions.

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

• Regular reflection occurs on rough surfaces, while diffuse reflection occurs on smooth surfaces.

What is the angle of incidence?

• The angle of incidence is the angle between the incident ray and the tangent to the surface at the point of incidence.

• The angle of incidence is the angle between the reflected ray and the normal to the surface at the point of incidence.

• The angle of incidence is the angle between the refracted ray and the normal to the surface at the point of incidence.

• The angle of incidence is the angle between the incident ray and the normal to the surface at the point of incidence.

Define the angle of reflection.

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

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

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

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

How does a mirror produce an image?

• By refracting light

• By reflecting light

• By absorbing light

• By emitting light

What is the difference between a concave and convex mirror?

• Concave mirrors can only create virtual images, while convex mirrors can only create real images.

• Concave mirrors always produce smaller images, while convex mirrors always produce larger images.

• Concave mirrors reflect light outwards, while convex mirrors reflect light inwards.

• Concave mirrors can create both real and virtual images, while convex mirrors can only create virtual images.

Explain the concept of focal point in a concave mirror.

• The focal point in a concave mirror is located outside the mirror.

• The focal point in a concave mirror is the point where the light rays do not converge.

• The focal point in a concave mirror is the point where parallel rays of light converge after reflecting off the mirror.

• The focal point in a concave mirror is where the light rays diverge after reflecting off the mirror.

What is the relationship between the object distance and image distance in a concave mirror?

• The relationship between the object distance and image distance in a concave mirror depends on whether the object is located within or beyond the focal point.

• The relationship between the object distance and image distance in a concave mirror is not affected by the mirror's curvature

• The relationship between the object distance and image distance in a concave mirror is always equal

• The relationship between the object distance and image distance in a concave mirror is determined by the color of the object

Describe how a convex mirror forms an image.

• The image formed by a convex mirror is virtual, inverted, and magnified.

• The image formed by a convex mirror is real, inverted, and magnified.

• The image formed by a convex mirror is real, upright, and magnified.

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

Explain the concept of virtual image in reflection.

• A virtual image in reflection is formed when light rays appear to originate from a point in front of the mirror

• A virtual image in reflection is formed when light rays appear to be parallel to the mirror surface

• A virtual image in reflection is formed when light rays appear to converge from a point behind the mirror

• A virtual image in reflection is formed when light rays appear to diverge from a point behind the mirror, even though no actual light is reaching that point.
