Answer: A and B

Explanation:

Electromagnetic radiations are examples of electromagnetic waves with increasing frequency and decreasing wavelength in the following order radiowaves - infrared waves - visible lights - ultraviolet rays - x-rays - gamma rays.

They did not require material medium for their propagation.

The statement above shows that EM radiations possesses different wavelengths and frequency.
