A wave is represented by the equation 
where x is in metre and t is in second. The expression represents
A
a wave travelling in positive 
-direction with a velocity 
-direction with a velocity B
a wave travelling in negative 
-direction with a velocity 
-direction with a velocity C
a wave travelling in the negative 
-direction having a wavelength 0.4 m
-direction having a wavelength 0.4 m D
a wave travelling in positive 
-direction of wavelength 0.1 m
-direction of wavelength 0.1 m
Text Solution
Verified by ExpertsThe correct answer is:
B
We have 
Positive sign between 
and 
means, wave is travelling in negative 
-direction.
