KCET · Physics · Electromagnetic Waves
The speed of electromagnetic wave in vacuum depends upon the source of radiation
- A increases as we move from \(\gamma\)-rays to radio waves
- B decreases as we move from \(\gamma\)-rays to radio waves
- C is same for all of them
- D None of the above
Answer & Solution
Correct Answer
(C) is same for all of them
Step-by-step Solution
Detailed explanation
Speed of electromagnetic waves in vacuum
\(=\frac{1}{\sqrt{\mu_{0} \varepsilon_{0}}}=\text { constant }\)
\(=\frac{1}{\sqrt{\mu_{0} \varepsilon_{0}}}=\text { constant }\)
