SI Units of Frequency, Wavelength, Velocity, and Time Period
Frequency:
- The SI unit of frequency is hertz (Hz).
- Frequency is defined as the number of complete cycles or oscillations of a wave that occur in one second.
- It is represented by the symbol "f" and is given by the equation f = 1/T, where T is the time period.
Wavelength:
- The SI unit of wavelength is meters (m).
- Wavelength is the distance between two consecutive points in a wave that are in phase with each other.
- It is represented by the symbol "λ" (lambda) and is usually measured in meters.
Velocity:
- The SI unit of velocity is meters per second (m/s).
- Velocity is defined as the rate of change of displacement of an object with respect to time.
- It is represented by the symbol "v" and is given by the equation v = d/t, where d is the displacement and t is the time taken.
Time Period:
- The SI unit of time period is seconds (s).
- Time period is the time taken for one complete cycle or oscillation of a wave to occur.
- It is represented by the symbol "T" and is usually measured in seconds.
Incorrect Statement:
The incorrect statement is (B) SI Unit of wavelength is ms-1.
- The SI unit of wavelength is meters (m), not meters per second (m/s).
- Wavelength represents the spatial characteristics of a wave, not its speed.
- Therefore, the correct SI unit of wavelength is meters (m), not meters per second (m/s).
Correct Answer:
The correct answer is option 'B' - (B) and (C) are incorrect.
Frequency:
- The SI unit of frequency is hertz (Hz).
- Frequency is defined as the number of complete cycles or oscillations of a wave that occur in one second.
- It is represented by the symbol "f" and is given by the equation f = 1/T, where T is the time period.
Wavelength:
- The SI unit of wavelength is meters (m).
- Wavelength is the distance between two consecutive points in a wave that are in phase with each other.
- It is represented by the symbol "λ" (lambda) and is usually measured in meters.
Velocity:
- The SI unit of velocity is meters per second (m/s).
- Velocity is defined as the rate of change of displacement of an object with respect to time.
- It is represented by the symbol "v" and is given by the equation v = d/t, where d is the displacement and t is the time taken.
Time Period:
- The SI unit of time period is seconds (s).
- Time period is the time taken for one complete cycle or oscillation of a wave to occur.
- It is represented by the symbol "T" and is usually measured in seconds.
Incorrect Statement:
The incorrect statement is (B) SI Unit of wavelength is ms-1.
- The SI unit of wavelength is meters (m), not meters per second (m/s).
- Wavelength represents the spatial characteristics of a wave, not its speed.
- Therefore, the correct SI unit of wavelength is meters (m), not meters per second (m/s).
Correct Answer:
The correct answer is option 'B' - (B) and (C) are incorrect.
