Question

Visible light has electromagnetic waves between:

• A. 8000 Å and 6000 Å
• B. 8000 Å and 1000 Å
• C. 8000 Å and 4000 Å
• D. 8000 Å and 2000 Å

Answer 1

The correct option is C

8000 Å and 4000 Å

An explanation for the correct option

1. The visible light is an electromagnetic wave.
2. It is the property of all the electromagnetic waves that they travel with the same speed equal to 3×10⁸m/s in a vacuum.
3. Visible light has wavelengths of electromagnetic waves between 8000 Å and 4000 Å.

Hence, option (c) 8000 Å and 4000 Å is the correct answer.
