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.

CS431 ASSIGNMENT 1 SOLUTION SPRING 2021

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.
