Question

Compare the speeds of light of wavelength 4000 angstrom and 8000 angstrom in vacuum

Answer 1

The speed of light is the same for all wavelengths in vacuum. According to Einstein's theory of relativity, the speed of light in vacuum is a constant value of 299,792,458 meters per second (or about 3 x 10^8 m/s). Therefore, the speeds of light with wavelengths of 4000 angstrom and 8000 angstrom are the same in vacuum and equal to 299,792,458 meters per second.

Answer 2

Step-by-step explanation:

The speed of light in a vacuum is constant and denoted by "c", which is approximately equal to 3 x 10^8 meters per second (m/s). The speed of light in a vacuum is not dependent on the wavelength of the light.

Therefore, the speed of light of wavelength 4000 angstrom and 8000 angstrom in vacuum is the same and is equal to the speed of light in a vacuum, which is approximately equal to 3 x 10^8 m/s.

In summary, the speeds of light of wavelength 4000 angstrom and 8000 angstrom in vacuum are identical and equal to the speed of light in a vacuum, which is approximately equal to 3 x 10^8 m/s.
