Question no.1 (five marks)

A wave of energy is transmitted fromthe source such as sender to receiver. It has an amplitude of 6.Eight cm, a time period of zero.01 seconds and the space from a crest to the neighboring trough of 14.8 cm. Via writing all necessary formulation and calculation steps, decide the frequency of this wave.

Answer: as we realize that

V = d/t = 0.148m/zero.01s = 14.8m/s

Now

V = f

So f = v/

F = 14.8m/s

6.8m = 2.18 hz

Query no. 2 (five marks)

Calculate the wavelength of a wave, having speed/pace identical to 30,000 nm/s and frequency identical to 60 hertz.

Answer: as we know that

V = 30,000nm/s = 30,000*10-9m/s = 0.3*10-4m/s

V = f

= v/f

= zero.3*10-4m/s

60hz = zero.1/2*10-four = 5*10-7m

Observe: write all vital formulation, calculation steps along with the ideal unit with your answer.

Question no.Three (5 marks)

Pick out one-way and -way verbal exchange examples from the following:

Instance one-way -manner

Radio one-manner

Cell phones -way

Television one-way

Wifi -manner

Walkie talkie -way

Query no.1 (5 marks)

A wave of energy is transmitted fromthe source such as sender to receiver. It has an amplitude of 6.Eight cm, a term of 0.01 seconds and the gap from a crest to the neighboring trough of 14.Eight cm. By using writing all important formulation and calculation steps, decide the frequency of this wave.

Solution: as we know that

V = d/t = 0.148m/0.01s = 14.8m/s

Now

V = f

So f = v/

F = 14.8m/s

6.8m = 2.18 hz

Question no. 2 (5 marks)

Calculate the wavelength of a wave, having velocity/speed identical to 30,000 nm/s and frequency identical to 60 hertz.

Solution: as we recognise that

V = 30,000nm/s = 30,000*10-9m/s = zero.3*10-4m/s

V = f

= v/f

= 0.3*10-4m/s

60hz = 0.0.5*10-four = five*10-7m

Be aware: write all essential formulation, calculation steps along side the appropriate unit with your answer.

Query no.3 (5 marks)

Identify one-manner and -manner conversation examples from the following:

Instance one-way -manner

Radio one-way

Cell phones two-way

Tv one-way

Wifi -manner

Walkie talkie two-manner

High-quality of success
