Introduction

In the realm of physics, photons are a fundamental concept that plays a crucial role in understanding various phenomena, from the behavior of light to the properties of matter. One of the key characteristics of photons is their energy, which is directly related to their frequency. In this article, we will delve into the calculation of the energy of a photon with a given frequency, using Planck's constant as a fundamental constant.

Planck's Constant and Photon Energy

Planck's constant, denoted by the symbol h{h}, is a fundamental constant in physics that relates the energy of a photon to its frequency. The formula for calculating the energy of a photon is given by:

E=hf{E = hf}

where E{E} is the energy of the photon, h{h} is Planck's constant, and f{f} is the frequency of the photon.

Calculating the Energy of a Photon

Given the frequency of the photon as 7.3×10−17 Hz{7.3 \times 10^{-17} \, \text{Hz}} and Planck's constant as 6.63×10−34 J⋅s{6.63 \times 10^{-34} \, \text{J} \cdot \text{s}}, we can calculate the energy of the photon using the formula:

E=hf=(6.63×10−34 J⋅s)×(7.3×10−17 Hz){E = hf = (6.63 \times 10^{-34} \, \text{J} \cdot \text{s}) \times (7.3 \times 10^{-17} \, \text{Hz})}

Performing the Calculation

To calculate the energy of the photon, we need to multiply the values of Planck's constant and the frequency of the photon.

E=(6.63×10−34 J⋅s)×(7.3×10−17 Hz){E = (6.63 \times 10^{-34} \, \text{J} \cdot \text{s}) \times (7.3 \times 10^{-17} \, \text{Hz})}

E=4.83×10−50 J{E = 4.83 \times 10^{-50} \, \text{J}}

Rounding to the Nearest Tenths Place

The calculated energy of the photon is 4.83×10−50 J{4.83 \times 10^{-50} \, \text{J}}. To round this value to the nearest tenths place, we need to look at the digit in the hundredths place, which is 3. Since 3 is less than 5, we round down to 4.8.

Conclusion

In conclusion, the energy of a photon with a frequency of 7.3×10−17 Hz{7.3 \times 10^{-17} \, \text{Hz}} and Planck's constant of 6.63×10−34 J⋅s{6.63 \times 10^{-34} \, \text{J} \cdot \text{s}} is 4.8×10−50 J{4.8 \times 10^{-50} \, \text{J}}. This calculation demonstrates the importance of Planck's constant in relating the energy of a photon to its frequency.
