Which of the following statements is false?

(a) MUF is always greater than or equal to critical frequency depending on the incident angle

(b) Optimum frequency is the frequency at which optimum reflection of wave takes place

(c) Beyond the MUF, the entire wave gets reflected back

(d) Below LUF, the entire power of wave gets absorbed

I have been asked this question in semester exam.

Origin of the question is Maximum Usable Frequency topic in division Virtual Height, Critical Frequency and Muf of Antennas

Best answer
Correct choice is (c) Beyond the MUF, the entire wave gets reflected back

Best explanation: Beyond MUF, (greater than critical frequency) the rays get penetrated into the region and no part of it is reflected back.
