The correct statement about the
Answer to Problem 1OQ
Option (c) and (d).
Explanation of Solution
Electromagnetic wave is the coupled propagation of electric field and magnetic field at right angles. An EM wave is the result of oscillation of a charged article.
Write the relation between frequency, wavelength and speed of wave in vacuum.
Here,
Conclusion:
It is correct that all electromagnetic waves travels at
It is the inherent property of an electromagnetic wave is that electric field and magnetic field is at right angles and normal to direction of wave propagation. Thus, option (d) is correct.
All electromagnetic waves cannot have same wavelength. Thus, option (a) is incorrect.
All electromagnetic waves cannot have same frequency. Thus, option (b)is incorrect.
Speed of electromagnetic wave through vacuum is independent of frequency. Thus, option (e) is incorrect.
