Question

E=hv
E=energy
h= Planck's constant =6.626 x 10^-34
v= frequency

1. What is the energy of light having a frequency of 2.28 x 10^12? ( I do have an answer for this but I'm not so sure about it.)

2.What is the energy of light with a wavelength of 2.18 x 10^-5?

3. A photon of light has an energy of 1.93 x 10^-24 J . What is its frequency

4. Calculate the wavelength of light with a frequency of 2.00 x 10^6 Hz..

5. What is the frequency of light with an energy of 8.48 x 10^-16 J?

6. How much energy does the light with a frequency of 7.9 x 10^11 Hz have?
I'm terrible at Chemistry

Answer 1

for 2) E=hv=h c/lambda
for 3) E=hv solve for v
for 4) f*lambda=speedlight solve for lambda
for 5) v=E/h
for 6) E=hv

This is not chemistry, it is math in chem.
