Answer:
b) twice the energy of each photon of the red light.
Explanation:
= Wavelength
h = Planck's constant =
c = Speed of light =
Energy of a photon is given by
Let = 700 nm
For red light
For UV light
Dividing the equations
Hence, the answer is b) twice the energy of each photon of the red light.
Work done against gravity to climb upwards is always stored in the form of gravitational potential energy
so we can say
here h = vertical height raised
so here we know that
here we have
now from above equation
so work done will be given by above value
