3. D9: I can compute derivatives of implicitly defined functions. D10: I can find the equation of the line tangent to a function at a point and use this line as a linear approximation to estimate the value of a function at nearby points. nteds Snell's Law or the Law of Refraction describes the behavior of light as it travels between two substances, telling us how light bends. Snell's law tells us about the relationship be- tween the angle of incidence, 01, and the angle of refraction, 02, as a ray of light travels from one medium to another and depends on the refrac- tion indices n₁ and n₂ of both of the substance. Snell's Law n₁ sin(01) = n2 sin (02) (a) Which letters represent variables? Air (1) 01 02 Glass (n2) (b) Which letters represent constants? d02 (c) (D9) Use Implicit differentiation to compute d01 (d) The refraction index of air is n₁ = 1 and the refraction index of glass is n2 = 1.52. If the angle of incidence is 0₁ = 20° verify that the angle of refraction is approximately 02 ≈ 13°. (Make sure you calculator is in degrees mode, and just plug in numbers to verify the equation balances.) (e) (D10) Find an equation for the tangent line when 0₁ = 20° and 62 = 13° (f) (D10) Use your tangent line to approximate the value of 02 when ₁ = 21°
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.
it is not graded!! the d9 and d10 are just standards!!
