Energy contained is maximum in

Options

A. visible light
B. radio waves
C. infrared rays
D. ultraviolet rays

Explanation

To solve the question regarding which type of light contains the maximum energy, we will follow these steps:

### Step 1: Understand the relationship between energy and frequency
The energy of a photon is directly proportional to its frequency. This relationship is given by the equation:
\[ E = h \nu \]
where:
- \( E \) is the energy of the photon,
- \( h \) is Planck's constant, and
- \( \nu \) (nu) is the frequency of the light.

### Step 2: Identify the frequencies of the given options
We have four types of light to consider:
1. Radio waves
2. Infrared
3. Visible light
4. Ultraviolet

Let's note the approximate frequency ranges for each:
- Radio waves: \( 10^5 \) Hz
- Infrared: \( 10^{12} \) Hz
- Visible light: \( 10^{15} \) Hz
- Ultraviolet: \( 10^{18} \) Hz

### Step 3: Compare the frequencies
Now we compare the frequencies:
- Radio waves have the lowest frequency.
- Infrared has a higher frequency than radio waves.
- Visible light has a higher frequency than infrared.
- Ultraviolet has the highest frequency among all four options.

### Step 4: Determine which type of light has the maximum energy
Since energy is directly proportional to frequency, the type of light with the highest frequency will have the maximum energy. From our comparison, ultraviolet light has the highest frequency.

### Conclusion
Therefore, the type of light that contains the maximum energy is:
**Ultraviolet (UV)**

### Final Answer
The answer is option 4: Ultraviolet.
