The amplitude of a plane progress wave = a that of a spherical progressive wave is (a/r) .

Q. The equation of a spherical progressive wave is

y = $α$ sin $ω$ t

y = $α$ sin ( $ω$ t - kr)

y = $\frac{a}{r}$ sin( $ω$ t - kr)

y = $\frac{a}{r}$ sin( $ω$ t - fr)

The amplitude of a plane progress wave = a that of a spherical progressive wave is $\frac{a}{r}$ .

Q. The equation of a spherical progressive wave is

y = α sin ω t

y = α sin ( ω t - kr)

y = r​a​ sin( ω t - kr)

y = ra​ sin( ω t - fr)

The amplitude of a plane progress wave = a that of a spherical progressive wave is ra​ .

y = $α$ sin $ω$ t

y = $α$ sin ( $ω$ t - kr)

y = $\frac{a}{r}$ sin( $ω$ t - kr)

y = $\frac{a}{r}$ sin( $ω$ t - fr)

The amplitude of a plane progress wave = a that of a spherical progressive wave is $\frac{a}{r}$ .
