Question

What is the wavelength of a 1.00-eV photon?

a. (1.24 × 10⁻⁶) m
b. (1.24 × 10⁻⁹) m
c. (1.24 × 10⁶) m
d. (1.24 × 10⁹) m

Answer 1

The wavelength of a 1.00-eV photon is approximately 1.24 x 10⁻⁶ m.

Step-by-step explanation:

The wavelength of a photon can be determined using the equation:

Wavelength = (Speed of light)/(Frequency)

Since we are given the energy of the photon, we can use the equation:

Energy = Planck's constant x Frequency

Plugging in the given energy of 1.00 eV and rearranging the equation, we can calculate the frequency of the photon. Then, using the speed of light value, we can calculate the wavelength.

Using these calculations, the wavelength of a 1.00-eV photon is approximately 1.24 x 10-6 m (option a).
