Tiny water droplets in the air disperse the white light of the sun into a rainbow. what is the energy of a photon from the
red portion of the rainbow if it has a frequency of 4.57 x 10s? ?

3.03 x 10⁻³² J

Explanation:

Data Given

Frequency of the light = 4.57 x 10 s⁻¹

Energy of the photon

Solution

Formula used

           E = hν

where

E = energy of photon

h = Planck's Constant

Planck's Constant = 6.626 x 10⁻³⁴ Js

ν = frequency

Put values in above equation

    E = hν

     E = 6.626 x 10⁻³⁴ Js x 4.57 x 10 s⁻¹

     E = 3.03 x 10⁻³² J

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

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