Pls mark me as brainliest Explanation:Light Properties - SHOWS the relationship between the speed of light, its wavelength and its frequency. A fairly SIMPLE, but important relationship. Formula: c =  f where:c = the speed of light = 300,000 km/s or 3.0 x 108 m/s = the wavelength of light, usually measured in meters or Ångströms (1 Å = 10-10 m)f = the frequency at which light waves pass by, measured in units of per seconds (1/s).This is a very important relationship since it tells you several things - first of all, the speed of light is constant - it never changes (as far as we're concerned in this class). So the LEFT side of the formula always has the same value. That means if you change something on the right side (either the wavelength or the frequency) then the other thing has to also change, but in the opposite sense. So if the wavelength goes down the frequency goes up, and vice versa.Typical Problems1. If a light's wavelength is increased by a factor of 10, how does its frequency change?Solution: Since the speed of light (c) cant change, when you change one part of the formula, the other part mush change in the opposite sense:c =  fSo for the left side to STAY the same while  becomes 10 times larger, f must become 10 times smaller. Mathematically this would be written asc = 10 x  x (1/10) fAnd the 10s cancel out. So f must be 10 times smaller.2. If a particular type of light has a wavelength of 6430 Å, what is its frequency?Solution: In order to use the formula, you should first convert the wavelength from Å to meters - 6430 Å = 6430 x 10-10 m = 6.430 x 10-7 mNow you can use it in the formula -c =  fRearrange it to solve for ff = c/f = 3 x 108/(6.430 x 10-7) = 4.67 x 1014 /seconds.3. If a particular type of light has a frequency of 1 million /second, what is its wavelength?Solution: Rearrange the formula to solve for wavelength - c =  f = c/fAnd put in the VARIOUS values, no conversions are needed, though you need to write frequency properly - = 3 x 108/ 106 = 300 m.
