Which of the following is TRUE regarding reflection and refraction? a. Reflection can be explained by the particle nature of light while refraction cannot. b. Refraction can be explained by the wave nature of light while reflection cannot. c. Reflection and refraction can be explained by both the wave and particle nature of light. d. Reflection and refraction can only be explained by the wave nature of light. The perception of color does not correspond to a unique set of wavelengths. The human eye distinguishes several hundreds of colors and shades. The eye has only three separate types of visual signals. So the different signal perceptions of colors are combinations of these three visual signals. Perception of colors depends upon the relative stimulation of the three color sensitive cells in the retina of the eye. What are the requirements for perceiving colors? a. Eye and light b. Eye, object, and light c. Eye, light, and shadow d. Eye, light, and medium
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.
