Question

The wave described by y = 0.25 sin (10???? x – 2???? t),
where x and y are in meters and t in seconds, is a
wave travelling along the:
(a) –ve x direction with frequency 1 Hz.
(b) +ve x direction with frequency ???? Hz and
wavelength ???? = 0. 2 m.
(c) +ve x direction with frequency 1 Hz and
wavelength ???? = 0.2 m
(d) –ve x direction with amplitude 0.25 m and
wavelength ???? = 0.2 m

Answer 1

Answer :- a) –ve x direction with frequency 1 Hz.

Answer 2

Explanation:

The wave described by y = 0.25 sin (10???? x – 2???? t),

where x and y are in meters and t in seconds, is a

wave travelling along the:

(a) –ve x direction with frequency 1 Hz.

(b) +ve x direction with frequency ???? Hz and

wavelength ???? = 0. 2 m.

(c) +ve x direction with frequency 1 Hz and

wavelength ???? = 0.2 m

(d) –ve x direction with amplitude 0.25 m and

wavelength ???? = 0.2 m
