Speed of light in water = speed of light in vacuum/refractive index of water
by dividing the speed of light with its wavelength
The speed of light in any medium isspeed of light in vacuum/refractive index of that medium.
Radar emissions are electromagnetic radiation that travel at the speed of light.
The formula used to calculate the speed of light is c = fλ, where c is the speed of light, f is the frequency of the light wave, and λ is the wavelength of the light wave. The speed of light in a vacuum is approximately 299,792 kilometers per second.
You can calculate frequency from wavelength using the equation: frequency = speed of light / wavelength. The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second. By dividing this speed by the wavelength of light in meters, you can determine the frequency in hertz.
Assuming the speed of light in air is already known (it is close to the speed of light in a vacuum), you might check how the light refracts when it changes from air to water (at what angle), and then use Snell's Law.
You can calculate the frequency of light using the formula f = c/λ, where f is the frequency, c is the speed of light (approximately 3.00 x 10^8 m/s), and λ is the wavelength of light. Simply divide the speed of light by the wavelength to find the frequency of light.
Light is faster than sound.
from the book
they get a computer and get it in slow motion and calculate it on the computer by km
To find the wavelength of light in Plexiglass, you need to take into account the change in speed of light. Since light travels at 67% of its speed in air in Plexiglass, you would need to calculate the wavelength using the formula: wavelength in Plexiglass = wavelength in air / refractive index of Plexiglass. Refractive index of Plexiglass is calculated as speed of light in air / speed of light in Plexiglass.
