NEET 2008 Physics question

The wave described by , where and are in meters and in seconds, is a wave travelling along the

(1)-ve direction with amplitude 0.25 m and wavelength m
(2)-ve direction with frequency 1 Hz
(3)+ve direction with frequency Hz and wavelength m
(4)+ve direction with frequency 1 Hz and wavelength mCorrect

Answer: (4)

Solution

Compare with the standard form of a wave travelling along : . The opposite relative signs of the and terms (i.e. ) mean propagation in the direction. $ = 10π ⇒
