Which of the following scientists developed equation E = hv?

Options

A. Einstein
B. Schrodinger
C. Max Planck
D. Newton

Explanation

To solve the question "Which of the following scientists developed the equation E = hv?", follow these steps:

### Step-by-Step Solution:

1. **Identify the Equation**: The equation in question is E = hv, where E represents energy, h is Planck's constant, and v (nu) represents frequency.

2. **Understand the Components**:
- **E (Energy)**: This is the energy of a photon.
- **h (Planck's Constant)**: This is a fundamental constant in quantum mechanics, approximately equal to 6.626 x 10^-34 Js.
- **v (Frequency)**: This refers to the frequency of the electromagnetic wave.

3. **Historical Context**: The equation E = hv was developed in the early 20th century as part of the quantum theory.

4. **Identify the Scientist**: The scientist who proposed this equation is **Max Planck**. He introduced this relationship in 1900 as part of his work on black-body radiation.

5. **Conclusion**: Therefore, the correct answer to the question is Max Planck.
