well... i think that light has a fixed speed (my assumption) 299,792,458 meters per second in a vacuum. But how to calculate the speed of anything is speed = distance/ time

To calculate he speed of light you need to know the refractive index (RI) of the medium through which it is travelling. As stated above light has a constant speed in a vacuum, this speed is attenuated by the refractive index of the given medium

What is the formula relating speed of light frequency and wavelength?

The formula relating the speed of light (c), frequency (f), and wavelength (λ) is: c = fλ. This formula shows that the speed of light is equal to the frequency multiplied by the wavelength.


What is the formula for the speed of light and which light between gamma rays and radio have the highest speed?

The formula for the speed of light, in vacuum, isc = 299,792,458 meters/second . where ' c ' is the speed of light.In any material substance, the speed of light isc/(the index of refraction for that substance) . Gamma rays, radio waves, and all other members of the electromagnetic spectrumbetween those, all have the same speed.


What is c in the wavelength formula?

In the wavelength formula, 'c' represents the speed of light in a vacuum, which is approximately 3.00 x 10^8 meters per second. This constant value is commonly used in physics and electromagnetic equations to determine the relationship between wavelength, frequency, and speed.


What is its wavelength in Plexiglass where light travels at 67 percent of its speed in air?

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.


How long would it take to travle 20 million light years?

Traveling 20 million light years at the speed of light would take 20 million years. Since we do not currently have technology that can travel at the speed of light, it would take much longer using current spacecraft technology.

How do you find the frequency from wavelength?

To find the frequency from wavelength, you can use the formula: frequency speed of light / wavelength.


What does celeritas mean?

Celeritas means 'at the speed of light'. In Einstein's formula E=MC2, the 'C2' stands for 'the speed of light times the speed of light, or, the speed of light times itself, or, the speed of light squared.
