Electromagnetic Waves and Light

Question 1

also known as ray optics, is a model used to describe the behavior of light in terms of rays. It simplifies the study of light propagation by approximating the paths along which light travels under certain circumstances.

Answer 1

Geometric Optics

Question 2

the angle of incidence (the angle at which light strikes a surface) is equal to the angle of reflection (the angle at which the reflected ray
bounces off the surface)

Answer 2

Law of Reflection

Question 3

Who proposed the Law of Reflection?

Answer 3

Pierre de Fermat

Question 4

also known as regular reflection, occurs when waves (such as light) reflect off a surface in a mirror-like manner

Answer 4

Specular Reflection

Question 5

also known as scattering, occurs when light reflects off a surface in many different directions rather than just one specific angle

Answer 5

Diffused Reflection

Question 6

These mirrors have a flat surface. The images formed in plane mirrors are identical to the object but reversed from left to right.

Answer 6

Plane Mirrors

Question 7

curved outward. The images produced by _____ mirrors are virtual, diminished, and erect (upright) for real objects.

Answer 7

Convex Mirrors

Question 8

are curved inward. The image obtained from ____ mirrors depends on the placement of the object.

Answer 8

Concave Mirrors
