Microwave ovens emit microwave energy with a wavelength of 12.5 cm. What is the energy of exactly one photon of this microwave radiation?

1.5891x10^-24

E = hc/wavelength

Remember to change cm to m for wavelength.

To determine the energy of one photon of microwave radiation, you can use the equation:

Energy (E) = Planck's constant (h) × Speed of light (c) / wavelength (λ)

The value of Planck's constant is approximately 6.626 x 10^-34 joule · seconds (J·s) and the speed of light is approximately 3.00 x 10^8 meters per second (m/s).

First, convert the wavelength from centimeters to meters:

12.5 cm = 12.5 × 10^-2 meters = 0.125 meters

Now, plug the values into the equation:

E = (6.626 x 10^-34 J·s) × (3.00 x 10^8 m/s) / 0.125 m

Calculating this expression will give you the energy of one photon of microwave radiation in joules.

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

Energy = Planck's constant (h) × Speed of light (c) / Wavelength

Planck's constant (h) = 6.626 × 10^(-34) J·s
Speed of light (c) = 3 × 10^8 m/s

First, convert the wavelength from centimeters to meters:

12.5 cm = 12.5 × 10^(-2) m = 0.125 m

Now we can calculate the energy of one photon:

Energy = (6.626 × 10^(-34) J·s) × (3 × 10^8 m/s) / (0.125 m)

Energy = 1.59408 × 10^(-23) J

Therefore, the energy of one photon of microwave radiation with a wavelength of 12.5 cm is approximately 1.59408 × 10^(-23) Joules.
