Question
The equation of the progressive wave is y = 3sin `[ pi("t"/3-x/5) + pi/4]`, where x and y are in metre and time in second. Which of the following is correct?
Options
Velocity v = 1.5 m/s
Amplitude A = 3 cm
Frequency f = 0.2 Hz
Wavelength λ = 10m
MCQ
Fill in the Blanks
Solution
Wavelength λ = 10m
Explanation:
Standard equation of wave motion,
Y = A sin `[2pi("t"/"T"-x/lambda)+pi/4]`
When compare the given equation with standard equation we get,
Amplitude A = 3 cm
Wavelength λ = 10m
