Final answer:
Using the equation E = hf where h is Planck's constant (6.626 x 10⁻³⁴ J·s) and f is the frequency (4.69 x 10⁴ Hz), the energy of one photon emitted by the laser is 3.11 x 10⁻¹⁵ joules.
Step-by-step explanation:
To calculate the energy of a single photon with a given frequency, we use the formula E = hf, where E is the energy of the photon in joules (J), h is Planck's constant, and f is the frequency of the light.
In this case, the frequency of the laser light is given as 4.69 x 10⁴ Hz. Planck's constant is approximately 6.626 x 10⁻³⁴ J·s.
Therefore, the energy of one photon of this radiation can be calculated as follows:
- E = h x f
- E = (6.626 x 10⁻³⁴ J·s) x (4.69 x 10⁴ Hz)
- E = 3.11 x 10⁻¹⁵ J per photon
In this computation, we find that the energy of one photon of light emitted from this laser is 3.11 x 10⁻¹⁵ joules.
