A
direction with frequency 1 Hz and wavelength 
B
−ve 
direction with amplitude 0.25 m and wavelength 
direction with amplitude 0.25 m and wavelength
C
−ve 
direction with frequency 1 Hz.
direction with frequency 1 Hz.
D
direction with frequency 
Hz and wavelength 
Text Solution
Verified by ExpertsThe correct answer is:
A
Hz
The sign is negative inside the bracket. Therefore, this wave travels in the positive 
‐direction.
