How much energy is in a length of 50 meters from the beam?
An argon-ion laser produces a beam of light with a power cylinder W. 0.750 average How much energy is contained in a 50 m length of the beam? You have to give me the answer, I just said the right track .. thanks!
This is strictly a SWAG, but 750W is a measure of power and energy (kwh) should (be) (timing). One possible answer is (power) (Time for light to travel 50 meters) (750) (50 / (3 * 10 ^ 8 m / sec)) = (1250) (10 ^ -8) watt_seconds You may need to convert to appropriate units.
