36)Morse code consists of 2 symbols dot and dash. If we use a set of 6 to represent any character or digit the total number that can be represented with that condition is ________

128

37)

The frequency of a microwave signal with 1 millimeter of wave length is ________ gigaHzs

3000000

38)

A microwave signal frequency is 60 gigahertz its wave length is: ________________ millimeter(s)

Solution

36.

2 symbol and 6 set of representation then 2^6 becomes 64

37.

1 wavelength in millimetres = 2.9979 x 10^14 millihertz
1 millihertz = 1 x 10^-6 kilohertz
1 kilohertz = 1 x 10^-3 megahertz
1 megahertz = 1 x 10^-3 gigahertz

1 wavelength in millimetres = 2.9979 x 10^14 x 10^-12 gigahertz
1 wavelength in millimetres = 2.9979 x 10^2 gigahertz
1 wavelength in millimetres = 299.79 gigahertz

38.

1 gigahertz = 299.79 wavelength in millimetres
60 gigahertz = (299.79)/60 wavelength in millimetres
60 gigahertz = 4.99 wavelength in millimetres
