Frequencies in the UHF(Ultra High Frequency) range normally propagate by means of:
Hence, frequencies in the UHF range normally propagate by means of space waves.
Frequencies in the UHF range normally propagate by means of:
(a) Ground waves.
(b) Sky waves.
(c) Surface waves.
(d) Space waves.
What do you mean by the audible range of frequency ?
For a transistor amplifier, the voltage gain
(a) remains constant for all frequencies.
(b) is high at high and low frequencies and constant in the middle frequency range.
(c) is low at high and low frequencies and constant at mid frequencies.
(d) None of the above.
