Determine the energy in joules or a photon with frequency of 5.78 x 10^17 hz

E= 3.829 x 10-16 J

Explanation:

Data Given

Frequency= 5.78 x 10^17 Hz

Energy in joules = ?

Solution:

Formula used to calculate Energy

E= hv…………….. (1)

Where E is Energy

h is Planks Constant = 6.626 x 10–34 J s

v is frequency

The given frequency is in Hz (Hertz)

Hz is equal to s-1 (per second)

1 hertz = 1 /second

Putting the values in Equation 1

E= (6.626 x 10–34 J s) (5.78 x 1017 s-1)

E= 3.829 x 10-16 J
