Mirror Characteristics and Reflection

What are the characteristics of plane mirrors?

• Real images, upright, smaller than object, located behind the mirror, not laterally inverted

• Real images, inverted, smaller than object, located in front of the mirror, not laterally inverted

• Virtual images, inverted, larger than object, located in front of the mirror, not laterally inverted

• Virtual images, upright, same size as object, located behind the mirror, laterally inverted

Explain the characteristics of convex mirrors.

• Convex mirrors form real, inverted, and magnified images.

• Convex mirrors are flat mirrors that converge light rays.

• Convex mirrors are curved mirrors that bulge outwards, diverge light rays, form virtual, upright, and diminished images, and have a wider field of view.

• Convex mirrors have a narrow field of view.

Describe the characteristics of concave mirrors.

• Concave mirrors do not magnify images

• Concave mirrors curve inward, converge light rays, can produce real or virtual images, magnify images, invert images beyond the focal point, and create virtual images between the mirror and the focal point.

• Concave mirrors always produce real images

• Convex mirrors curve outward

What is regular reflection?

• The reflection of sound waves from a rough surface.

• The absorption of light by a transparent material.

• The refraction of light through a prism.

• The reflection of light from a smooth surface at a definite angle.

Define diffused reflection.

• Diffused reflection results in a single angle of reflection

• Diffused reflection only occurs on perfectly smooth surfaces

• Diffused reflection is the reflection of light in a straight line

• Diffused reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than reflected at just one angle.

What are some common uses of mirrors?

• Cooking utensils, Musical instruments, Transportation vehicles

• Personal grooming, interior decoration, optical instruments, scientific experiments

How does a plane mirror form an image?

• By reflecting light rays off its surface

• By absorbing light rays

• By emitting light rays

• By refracting light rays

What type of reflection occurs in a mirror maze?

• Irregular reflection

• Regular reflection

• Diffuse reflection

• Refracted reflection

Why are mirrors used in telescopes?

• To reflect and focus light, gather more light, and increase resolution.

• To play music

• To make phone calls

• To cook food

Explain how mirrors are used in periscopes.

• Mirrors in periscopes are used to project images onto a screen for viewing.

• Mirrors in periscopes reflect light multiple times to allow viewing objects not in direct line of sight.

• Mirrors in periscopes are used to emit light for better visibility.

• Mirrors in periscopes are used to create a holographic image of the surroundings.
