1. Frequency:
The energy given is the energy per mole of particles:
1 mole contains a number of Avogadro of particles, , equal to
particles
So, by setting the following proportion, we can calculate the energy of a single photon:
This is the energy of a single photon; now we can calculate its frequency by using the formula:
where
is the Planck's constant
f is the photon frequency
Solving for f, we find
2. Wavelength:
The wavelength of the photon is given by the equation:
where
is the speed of the photon (the speed of light). Substituting,
Answer:
The energy of the capacitors connected in parallel is 0.27 J
Given:
C =
C' =
Potential difference, V = 300 V
Solution:
Now, we know that the equivalent capacitance of the two parallel connected capacitors is given by:
The energy of the capacitor, E is given by;
