What is the energy of a photon (in units of h) that has a wavelength of 300 nm?
(c = 3.00 x 108 m/s)

1 x 10^17 h
1 x 10^15 h
1 x 10^6 h
1 x 10^-2 h

Explanation:

Considering:-

Where,  

h is Planck's constant having value

c is the speed of light having value

is the wavelength of the light

Given, Wavelength = 300 nm

Also, 1 m = nm

So,  

Wavelength = m

Applying in the equation as:-

the correct answer would be b) volume versus temperature, because they are also directly proportional.
