What makes raindrops appear as intense targets on radar screens?

Absorption of radar pulses
Reflection of radar energy
Emission of radio signals
Scattering of radar pulses

The correct answer is: Reflection of radar energy

Raindrops appearing as intense targets on radar screens is due to their ability to reflect radar energy. This is because radar beams are reflected by objects with a shape and size similar to the wavelength of the radar signal, and raindrops are often around the same size as the radar wavelength. Option A, absorption of radar pulses, would result in a weaker or non-existent signal on the radar screen. Option C, emission of radio signals, does not play a role in the appearance of raindrops on the radar screen. Option D, scattering of radar pulses, may contribute to the overall appearance of rain on the radar screen, but it is not the main factor in causing raindrops to appear as intense targets.
