Question

Calculate the amount of energy That an obsect Can absorb from Yellow light Whose wave length is 589 nm.​

Answer 1

Explanation:

E = hf

c= f × lamda

f= c/ lamda

c= speed of light

f= frequency

lamda = wavelength

E = h c/ lamda

E = 6.626 × 10^-34 Js × 3 × 10^8 ms-1 / 589 × 10^-9 m

= 3.37 × 10^15 J
