Physics Quiz: Reflection, Refraction, Mirrors, and Lenses

What type of mirror is used in a makeup mirror? (Concave or Convex)

• Flat

• Concave-convex hybrid

• Spherical

• Concave

Explain the difference between a concave and a convex mirror in terms of their reflective surfaces.

• Concave mirrors have a flat surface, while convex mirrors have a curved surface.

• Concave mirrors curve outward, while convex mirrors curve inward.

• Concave mirrors reflect light in a straight line, while convex mirrors reflect light in a scattered manner.

• Concave mirrors curve inward, while convex mirrors curve outward.

What type of mirror is used in a security mirror to provide a wider field of view? (Concave or Convex)

• Concave

• Transparent

• Flat

• Convex

What type of image is formed by a concave mirror when the object is located beyond the focal point?

• Virtual, inverted, and enlarged in size

• Real, inverted, and reduced in size

• Real, upright, and enlarged in size

• Virtual, upright, and reduced in size

Explain the concept of a virtual image and provide an example of where it is commonly observed.

• A virtual image is an image formed by the apparent intersection of light rays that do not actually converge. It is commonly observed in a plane mirror.

• A virtual image is a physical object that can be touched and felt. It is commonly observed in a hologram.

• A virtual image is an image formed by the actual convergence of light rays. It is commonly observed in a concave mirror.

• A virtual image is an image that can only be seen by one eye. It is commonly observed in a convex lens.

A diverging lens forms an image that is virtual, upright, and reduced in size. What type of image is this?

• Virtual image

• Real image

• Inverted image

• Enlarged image

Describe the characteristics of a real image formed by a convex lens.

• Upright, located on the opposite side of the lens from the object, and cannot be projected onto a screen

• Sideways, located on the same side of the lens as the object, and can be projected onto a screen

• Inverted, located on the opposite side of the lens from the object, and can be projected onto a screen

• Upright, located on the same side of the lens as the object, and cannot be projected onto a screen

Explain the concept of total internal reflection and provide an example of where it occurs.

• Total internal reflection occurs when light passes from a medium with a higher refractive index to a medium with a lower refractive index at an angle greater than the critical angle. An example of this is the mirage effect in deserts.

• Total internal reflection occurs when light passes from a medium with a lower refractive index to a medium with a higher refractive index at an angle greater than the critical angle. An example of this is the formation of rainbows.

• Total internal reflection occurs when light passes from a medium with a higher refractive index to a medium with a lower refractive index at an angle less than the critical angle. An example of this is the refraction of light in a glass prism.

• Total internal reflection occurs when light passes from a medium with a lower refractive index to a medium with a higher refractive index at an angle less than the critical angle. An example of this is the dispersion of light in a glass prism.
