15. How many photons are emitted by a 5.00 mW laser in 10.0 s if the photons have a wavelength of 649 nm? 1.86x1019 1.63x1020 1.16x1038 1.63×1017 16. An object is placed 35.0 cm from a diverging lens that has a focal length of 20.0 cm. The image produced is real and larger than the object virtual and larger than the object real and smaller than the object virtual and smaller than the object Use the following information to answer the next question A group of students conducted a series of test to determine which combination of optical media results in the largest critical angle for one wavelength of visible light. The table shown lists the index of refraction for each of the media used.
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.
