Question

If a particular electromagnetic wave has the highest frequencies among the other electromagnetic waves then it should have the smallest

• A. wavelengths
• B. speeds
• C. amplitudes
• D. energies
• E. periods

Answer 1

The correct option is A wavelengths

Electromagnetic waves travel with constant speed equal to that of light i.e $v=c=constant$

For EM waves $\lambda \times \nu =c=$ constant

Thus waves with highest frequency will have smallest wavelength.
