**Question:** What is the energy of a photon of light with a wavelength of 469 μm?

---

This question involves calculating the energy of a photon based on its wavelength, which is 469 micrometers (μm). To find the energy, use the equation:

\[ E = \frac{h \cdot c}{\lambda} \]

Where:
- \( E \) is the energy,
- \( h \) is Planck's constant (\(6.626 \times 10^{-34} \, \text{J}\cdot\text{s}\)),
- \( c \) is the speed of light (\(3.00 \times 10^{8} \, \text{m/s}\)),
- \( \lambda \) is the wavelength in meters.

First, convert the wavelength from micrometers to meters:

\[ \lambda = 469 \, \mu\text{m} = 469 \times 10^{-6} \, \text{m} \]

Next, substitute the values into the equation:

\[ E = \frac{6.626 \times 10^{-34} \times 3.00 \times 10^{8}}{469 \times 10^{-6}} \]

Calculate to find the energy \( E \).

Expert Solution
Interpretation Introduction

Interpretation: The energy of a photon of light with a wavelength of 469 μm is to be determined.

Concept Introduction: The energy of a photon is proportional to its frequency, as stated by the Planck's Einstein's equation,

E = h·ν

Where,

E - the energy f the photon

h - Planck's constant = 6.626 · 10-34 Js

v - The frequency of the photon
