Question

what is wavelength , timeperid, reverbation, longitudinal wave, mechanical wave, Newton's law

Answer 1

Wave length is the distance between the succsive crests of a wave
Tmie period is the time in which one complete cycle passes to a given point
Reverberation is the prongation of sound
Longitudinal wave is wave which is vibrating in the direction of propagation
Mechanical wave is an oscillation of matterand therefore transfers energy through medium
Newtons law First Lawstates that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force 2nd law states The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
3rd law stated to every action there is an equal and opp reaction..
