Calculate the number of photons emitted each second from a laser pointer. the 17.7 milliwatt laser pointer is green, with a wavelength of exactly 532 nm. note: to input large numbers (scientific notation) into canvas, you will need to use "e" for example, 1 billion > 1e9 note: required precision is 2%.

Explanation:

given data:

power = 17.7 milliwatt

p = 17.7 *10^{-3} watt

wavelength = 532 nm = 532*10^{-9} m

energy of photon

h is plank constant = 6.626*10^{-34} JOULE/SEC

C =3*10^8 m/sec

let n is m=number of photon emiited per sec

we knwo that

p = ne

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
