Given information:
Frequency of the source = 500 Hz
Wavelength of the waves = 0.4 m
Distance traveled by the waves = 600 m
To find: Time taken by the waves to travel 600 m
Speed of the wave:
The speed of a wave can be calculated using the formula:
Speed = Frequency × Wavelength
Given that the frequency is 500 Hz and the wavelength is 0.4 m, we can substitute these values into the formula to find the speed of the wave.
Speed = 500 Hz × 0.4 m
Speed = 200 m/s
Time taken by the wave to travel a distance:
The time taken by the wave to travel a distance can be calculated using the formula:
Time = Distance ÷ Speed
Given that the distance is 600 m and the speed is 200 m/s, we can substitute these values into the formula to find the time taken by the wave.
Time = 600 m ÷ 200 m/s
Time = 3 s
Therefore, the waves take 3 seconds to travel a distance of 600 m.
Answer: a) 3 s
Frequency of the source = 500 Hz
Wavelength of the waves = 0.4 m
Distance traveled by the waves = 600 m
To find: Time taken by the waves to travel 600 m
Speed of the wave:
The speed of a wave can be calculated using the formula:
Speed = Frequency × Wavelength
Given that the frequency is 500 Hz and the wavelength is 0.4 m, we can substitute these values into the formula to find the speed of the wave.
Speed = 500 Hz × 0.4 m
Speed = 200 m/s
Time taken by the wave to travel a distance:
The time taken by the wave to travel a distance can be calculated using the formula:
Time = Distance ÷ Speed
Given that the distance is 600 m and the speed is 200 m/s, we can substitute these values into the formula to find the time taken by the wave.
Time = 600 m ÷ 200 m/s
Time = 3 s
Therefore, the waves take 3 seconds to travel a distance of 600 m.
Answer: a) 3 s
