Answer to Problem 59A

Theeyes of the aliens are smaller than us.

Explanation of Solution

Introduction:

Microwaves are a form of electromagnetic radiation with the frequency range between 300 MHz and 300 GHz. Microwave fall between the infrared radiation and radio waves in the EM spectrum.

The alien eyes are very sensitive to microwaves. That means they can receive even weak signal. The weak signals can be collected and focused only if the surface area is very large. Thus, one can expect that the eyes of the alien would be larger than eyes of the human being.

Conclusion:

Hence, the eyes of the aliens are smaller than us.
