Question

The energy of green light whose frequency is 6 multiply 10^14 is :

Answer 1

Answer:

3.972 × 10^21

Explanation:

E=hv

h=planks constant =6.62×10^-34 m^2kg /s

v= frecuency = 6×10^14

E = ( 6.62×10^-34 )×(6×10^14)

= 3.972 × 10^21

Answer 2

Answer:

The energy of green light at the given frequency is 3.972 × 10^-19 Joules.

Explanation:

According to Planck's equation,

E=hv, where E is the Energy, h is the Planck's constant and v is the frequency of the given light.

Value of h is - 6.62×10^-34 Joule-seconds(J-s)

The frequency is given as 6×10^14 Hertz

Now solving the equation by putting the given values:

E = ( 6.62×10^-34 ) × (6×10^14)

= 39.72 × 10^-20 Joules or 3.972 × 10^-19 Joules.
