- An intense light source radiates uniformly in all directions. At a distance of 6 m from the source, the radiation pressure on a perfectly absorbing surface is 5.0 x 10-6 Pa. What is the total average power output of the source? (kW)An intense light source radiates uniformly in all directions. At a distance of 5.0m from source, the radiation pressure on a perfectly absorbing surface 9 micro pascals. What is the total average power output of the source?In a vacuum, red light has a wavelength of 700 nm and violet light has a wavelength of 400 nm. This means that in a vacuum, red light has higher frequency has lower frequency frequency will be energy dependent O has higher frequency and moves faster than violet light. O has lower frequency and moves faster than violet light.
