What is the wavelength of light that has a frequency of 6 x 10 14 Hz? Its wavelength is : (a) 500 nm. What is the wavelength of a photon of red light in NM whose frequency is 4.55 x 1014 Hz? Thus, the wavelength of photon of the red light is 657.89 nm. What […]
Why is the work output of a machine always less than the work input?
Why is the work output of a machine always less than the work input? Although nearly equal, the output work is less than the input work because of friction. All machines use some amount of input work to overcome friction. The only way to increase the work output is to increase the amount of work […]
