A cook uses a microwave oven to heat meal. The wavelength is 3.30cm. what is the energy of one photon of this microwave radiation?

Answer 1

To calculate the energy of one photon, we can use the equation:

E = hc/λ,

where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J.s), c is the speed of light (2.998 x 10^8 m/s), and λ is the wavelength of the radiation.

First, we need to convert the wavelength from centimeters to meters:

λ = 3.30 cm = 0.033 m.

Now we can calculate the energy of one photon:

E = (6.626 x 10^-34 J.s * 2.998 x 10^8 m/s) / 0.033 m.

E = 6.022 x 10^-24 J.

Therefore, the energy of one photon of this microwave radiation is approximately 6.022 x 10^-24 Joules.
