Refraction of Light
Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.
Angle of Refraction
Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.
Index of Refraction of Diamond
Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.
Question
Transcribed Image Text:Learning Goal:
To learn and practice the geometry skills necessary for
complex reflection setups.
The law of reflection has the very simple form
Oreflected,
Vincident
=
where incident is the angle between the normal and the
incident ray and reflected is the angle between the normal
and the reflected ray. Although the law itself is easy to
use, many realistic situations involve successive
reflections from multiple surfaces. The law of reflection
does not become any more complicated in such cases,
but the geometry of the rays does become complicated.
Consider the case of light shining onto a mirror, which is
attached to another mirror at some angle a, as shown in
the figure (Figure 1). In this problem, we will find the angle
at which light leaves the arrangement of two mirrors.

Part A
If the light strikes the first mirror at an angle 0₁, what is the reflected angle 02?
Express your answer in terms of 0₁.
0₂ = 0₁

Part B
Correct
Previous Answers
Now, find the angle 03 (shown in the new figure (Figure 2)) in terms of 0₁. You can easily fi
02, then just substitute your expression from Part A.
03 =
Express your answer in terms of 0₁ and any numerical angles. When entering numer
assume the value is in degrees, so just use the number "23" to indicate 23 degrees.
