Photon of which light has maximum energy :

Options

A. red
B. blue
C. violet
D. green

Explanation

To determine which light has the maximum energy, we need to understand the relationship between the energy of a photon and its wavelength. The energy of a photon can be calculated using the formula:

\[ E = \frac{hc}{\lambda} \]

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

### Step-by-Step Solution:

1. **Understand the Electromagnetic Spectrum**:
- The electromagnetic spectrum consists of various types of light, including gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, and radio waves.
- Among visible light, the colors range from violet (shortest wavelength) to red (longest wavelength).

2. **Identify Wavelengths of Visible Light**:
- The order of visible light from shortest to longest wavelength is:
- Violet (approximately 380-450 nm)
- Indigo (approximately 450-475 nm)
- Blue (approximately 475-495 nm)
- Green (approximately 495-570 nm)
- Yellow (approximately 570-590 nm)
- Orange (approximately 590-620 nm)
- Red (approximately 620-750 nm)

3. **Relate Wavelength to Energy**:
- Since energy is inversely proportional to wavelength, shorter wavelengths correspond to higher energy.
- Therefore, among the visible light spectrum, violet light has the shortest wavelength and thus the highest energy.

4. **Conclusion**:
- Based on the analysis, the photon of violet light has the maximum energy among the visible spectrum.

### Final Answer:
The photon of violet light has the maximum energy.
