The colour of light which has maximum frequency is

Options

A. Blue
B. Red
C. Green
D. Violet

Answer

To determine the color of light that has the maximum frequency, we can follow these steps:

### Step 1: Understand the Visible Spectrum
The visible spectrum of light consists of colors that can be seen by the human eye, typically represented by the acronym "VIBGYOR," which stands for Violet, Indigo, Blue, Green, Yellow, Orange, and Red.

### Step 2: Identify the Energy-Frequency Relationship
The energy (E) of light is related to its frequency (ν) by the equation:
\[ E = h \nu \]
where \( h \) is Planck's constant. This equation tells us that energy is directly proportional to frequency. Therefore, as the frequency increases, the energy also increases.

### Step 3: Determine the Order of Colors by Energy
In the visible spectrum, the order of colors from highest energy (and frequency) to lowest energy (and frequency) is:
- Violet (highest energy and frequency)
- Indigo
- Blue
- Green
- Yellow
- Orange
- Red (lowest energy and frequency)

### Step 4: Conclude the Color with Maximum Frequency
Since violet is the color with the highest energy in the visible spectrum, it also has the maximum frequency.

### Final Answer
The color of light which has maximum frequency is **Violet**.
