In vacuum, the speed of all types of electromagnetic radiation is equa

1.	In vacuum, the speed of all types of electromagnetic radiation is equal to ………….(A) 3.0 × 106 m s-1(B) 3.0 × 108 m s-1(C) 3.0 × 1010 m s-1 (D) 3.0 × 1012 m s-1
Answer» Correct option is (B) \(3.0 × 10^8 m s^{-1}\) In vacuum , the speed of all types of electromagnetic radiation is equal to \(3.0 \times 10^8 \ m/s\). The speed of radiation depends on the medium. Option : (B) 3.0 × 10⁸ m s^-1

In vacuum, the speed of all types of electromagnetic radiation is equal to ………….(A) 3.0 × 106 m s-1(B) 3.0 × 108 m s-1(C) 3.0 × 1010 m s-1 (D) 3.0 × 1012 m s-1

Answer»

Correct option is (B) \(3.0 × 10^8 m s^{-1}\)

In vacuum , the speed of all types of electromagnetic radiation is equal to \(3.0 \times 10^8 \ m/s\). The speed of radiation depends on the medium.

Option : (B) 3.0 × 10⁸ m s^-1
