59cm

Explanation:

angular velocity = 0.8 rad/s

linear velocity = angular velocity * radius

=0.8rad/s * 5m

= 4 m/s

wavelength = (V + U) / F

where,

V is the velocity of the wave

U is the velocity of the source

F is the frequency of the source.

wavelength = (350 m/s + 4 m/s) / 600 Hz

Wavelength = 0.59m or 59 cm
