Which of the following statements concerning light is false?

Options

A. It is a form of energy
B. It cannot be deflected by a magnet
C. It consists of photons of same energy
D. It is a part of electromagnetic spectrum.

Explanation

To determine which statement concerning light is false, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding the Nature of Light**:
- Light is a form of electromagnetic radiation that is visible to the human eye. It consists of particles called photons.

2. **Evaluating Each Statement**:
- **Statement 1**: "It is a form of energy."
- This statement is true. Light is indeed a form of energy, and we can express its energy using the equation \( E = h\nu \), where \( E \) is energy, \( h \) is Planck's constant, and \( \nu \) (nu) is the frequency of the light.

- **Statement 2**: "It cannot be deflected by a magnet."
- This statement is also true. Light, being electromagnetic radiation, does not carry a charge and thus is not affected by magnetic fields. Only charged particles (like electrons) are deflected by magnets.

- **Statement 3**: "It consists of photons of same energy."
- This statement is false. Light consists of photons that can have a range of energies, depending on their frequency. For example, different colors of light correspond to different energies of photons.

- **Statement 4**: "It is a part of the electromagnetic spectrum."
- This statement is true. Visible light is indeed a part of the electromagnetic spectrum, which includes a range of wavelengths from radio waves to gamma rays.

3. **Identifying the False Statement**:
- After evaluating all the statements, we find that **Statement 3** is the false statement because light does not consist of photons of the same energy; it can consist of photons with varying energies.

### Final Answer:
The false statement concerning light is: **"It consists of photons of same energy."**
