Plz help on last question i asked Help PLEASE!! Will mark Calculate the total energy in 1.5 x 10^13 photons of gamma radiation having wavelength = 3.0 x 10^-12 m. Need to show ALL work.

The total energy but the photons will give is 6.615 x 10^-14

Explanation:

Formula that can be used in this question is E= hf or E= hc/ λ

This is the formula that can be used to calculate the energy that the photon is carrying where it is given as the Planck's Constant .

Now putting the values given in the equation that can calculate energy we get Planck's Constant is equal to 6.62 x 10^-34

E=(6.62 x 10^-34 x 2.998 x 10^8) / ( 3 x 10^-12 )

E=6.615 x 10^-14

The total energy but the photons will give is 6.615 x 10^-14

Explanation:

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
