Which of the following is the correct arrangement of wavelength in increasing order ?

Options

A. Yellow, orange, green, violet
B. violet, green, yellow, orange
C. green, yellow, orange, violet
D. violet, yellow, orange, green

Explanation

To solve the question regarding the correct arrangement of wavelengths in increasing order, we will follow these steps:

### Step 1: Understand the Electromagnetic Spectrum
The electromagnetic spectrum consists of various types of electromagnetic waves, including visible light. The visible spectrum is made up of different colors, which can be arranged in order of their wavelengths.

### Step 2: Identify the Colors in Visible Light
The colors of visible light, in order of increasing wavelength, are:
- Violet
- Indigo
- Blue
- Green
- Yellow
- Orange
- Red

### Step 3: Determine the Wavelengths of Given Colors
From the question, we have the following colors:
- Yellow
- Orange
- Green
- Violet

We need to know their relative wavelengths:
- Violet has the shortest wavelength.
- Green has a longer wavelength than violet.
- Yellow has a longer wavelength than green.
- Orange has the longest wavelength among the four.

### Step 4: Arrange the Colors in Increasing Order of Wavelength
Based on the information above, we can arrange the colors in increasing order of wavelength:
1. Violet (shortest wavelength)
2. Green
3. Yellow
4. Orange (longest wavelength)

Thus, the correct arrangement of the colors in increasing order of wavelength is:
**Violet < Green < Yellow < Orange**

### Step 5: Identify the Correct Option
According to the arrangement we derived, the correct option from the provided choices is the one that lists the colors in the order of:
**Violet, Green, Yellow, Orange.**

### Final Answer
The correct arrangement of wavelength in increasing order is:
**Violet < Green < Yellow < Orange.**
