What is the energy of a photon of green light with a frequency of 5.96 ✕ 1014 s-1?

Question

anonymous · Answer

use this equasion  E=hf.

anonymous · Answer

equation*

anonymous · Answer

Can you help as to what I plug in for those variables?

anonymous · Answer

ok so h = Planck's constant = 6.63 x 10^-34 J s and your frequency is given and is equal to 5.96 ✕ 1014.now just miltiply.

anonymous · Answer

Would it be the same equation for "Calculate the energy of a photon of red light with a wavelength of 6.39 ✕ 10-5 cm." ?

doc.brown · Answer

Yes.  Same formula.  You may also use v to represent frequency, but it's the same math.$$E=hv$$

doc.brown · Answer

$$E=6.63\times 10^-34J\cdot s\times\frac{6.39\times 10^{-5}}{s}=4.24\times 10^{-38}J$$

anonymous · Answer

Oh! That makes sense! Thank you!!

anonymous · Answer

In the problem below, what does the s-1 mean?
"Calculate the energy of a photon of green light with a frequency of 5.80 ✕ 1014 s-1"

joannablackwelder · Answer

s-1 means per second, as in waves per second.

doc.brown · Answer

$$x^{-n}=\frac{1}{x^n}$$so$$s^{-1}=\frac{1}{s}$$I'll just say, I use it exclusively.  I never write m/s unless I'm explaining something to someone else.  In my own work I write$$m\cdot s^{-1}$$
