You are a detective interviewing someone who says that (while sitting on a porch that you know to be 600ft away) he saw the masked suspect commit the crime in broad daylight. "How do you know it was the suspect?" you ask. "I clearly saw the 'MOM' that is tattooed on his upper arm." "You're sure it was that particular tattoo and not some other tattoo?" "Yes, I'm sure," The witness replies. The suspect's tattoo has letters that are 6cm tall. Is the witness credible, or might he be framing the suspect? Justify your response and any estimates you might make.
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.
