Question

In visible spectrum, which colour has larger wavelength ?

• A. Red
• B. Yellow
• C. Blue
• D. Violet

Hint:

Use the acronym VIBGYOR to remember the order of colors in the visible spectrum. The order goes from the shortest wavelength (Violet) to the longest wavelength (Red). This also means Violet light has the highest frequency and energy, while Red light has the lowest.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. It consists of a range of colors, each corresponding to a different wavelength of light. The question asks to identify the color with the largest wavelength.
Step 2: Detailed Explanation:
The colors of the visible spectrum are typically remembered by the acronym VIBGYOR, which stands for Violet, Indigo, Blue, Green, Yellow, Orange, and Red.
This sequence is arranged in order of increasing wavelength (or decreasing frequency and energy).
- Violet has the shortest wavelength (around 400 nm).
- Red has the longest wavelength (around 650-700 nm).
Therefore, among the given options, Red has the largest wavelength.
Step 3: Final Answer:
In the visible spectrum, Red has the largest wavelength. So, option (A) is correct.
