Speed of light in water 225 10⁸ m sec. Plug the known quantities into the equation and solve. N c v.
Find the wavelength of a wave traveling at 20 ms at a frequency of 5 Hz.
Calculating the Speed of Light Through Hand Sanitizer. One of the most important parameters that measures optical properties of a medium is the index of refraction. Snells law the law of refraction is stated in equation form as n 1 sin th 1 n 2 sin th 2. This index measures how much the medium alters the course that the light travels through reflection refraction occlusion or other obstruction.
