Answer:
Increase in total energy will be equal to the increase in the internal energy i.e Joules
Explanation:
Given
Weight of sledge hammer kilogram
Speed of sledge hammer meter per second
Kinetic energy is equal to half the product of mass and velocity square
Substituting the value of mass and velocity, we get -
It is given that one fourth of the energy is converted into internal energy
One fourth of kinetic energy is equal to
Increase in total energy will be equal to the increase in the internal energy i.e Joules
The relationship between frequency and wavelength for an electromagnetic wave is
where
f is the frequency
is the wavelength
is the speed of light.
For the light in our problem, the frequency is
, so its wavelength is (re-arranging the previous formula)
where
f is the frequency
For the light in our problem, the frequency is
