1. What Are Wavelength, Frequency And Energy?

Wavelength, frequency, and energy are fundamental properties of light and other electromagnetic waves. Wavelength (λ) is the distance between wave peaks, frequency (f) is how many waves pass per second, and energy (E) is the amount of energy carried by each photon of light.

2. How Does The Calculator Work?

The calculator uses two simple equations:

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

Where:

\( E \) — Energy in joules (J)
\( h \) — Planck's constant = 6.626×10⁻³⁴ J·s
\( f \) — Frequency in hertz (Hz)
\( \lambda \) — Wavelength in meters (m)
\( c \) — Speed of light = 3×10⁸ m/s

Explanation: Higher frequency light has more energy and shorter wavelength. Lower frequency light has less energy and longer wavelength.

3. Importance Of Light Energy Calculation

Details: Understanding these relationships helps scientists study light, design technologies like lasers and fiber optics, and understand how different types of light interact with matter.

4. Using The Calculator

Tips: Enter the frequency of light in hertz (Hz). The calculator will show you both the energy of each photon and the wavelength of the light. Frequency must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a photon?
A: A photon is a tiny particle of light that carries energy. Light is made of many photons.

Q2: Why does higher frequency light have more energy?
A: Each photon of high-frequency light vibrates faster, which means it carries more energy than photons of low-frequency light.

Q3: What are some examples of different light frequencies?
A: Radio waves have low frequency, visible light has medium frequency, and X-rays have very high frequency.

Q4: How small is the energy of a single photon?
A: Very small! A photon of visible light has about 0.0000000000000000001 joules of energy - that's why we need special units to measure such tiny amounts.

Q5: Can light have both wave and particle properties?
A: Yes! This is called wave-particle duality. Light behaves like waves in some experiments and like particles in others.
