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

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

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
