Here are two questions I am stuck on:(adsbygoogle = window.adsbygoogle || []).push({});

1. How many visible photons are produced per second from a 2Watt lamp? It says the range of the wavelengths is near 5x10^-7m. I tried this and got 3.33x10^33Hz but apparently thats wrong so please help me.

2. A photon of frequency 6x10^14Hz explores a path 6m long. Find the time of travel and the number of rotations of the phasor. This one I dont have a clu how to start but if I get the first answer I can easily work out the number of rotations of the phasor.

Please help me as I am really stuck...physics is really hard on this AS course. Thanks for all your help
