A sound source and a listener are both at rest on the earth , but a strong wind is blowing from the source towards the listener. Is there a Doppler effect ? Why or why not ?

If earth is revolving in elliptical orbit around sun, then which of the following quantity remains constant w.r.t.

If earth is revolving in elliptical orbit around sun, then which of the following quantity remains constant w.r.t.

Assertion : There will be no Doppler effect,when both the source and listener are at rest and wind alone is blowing Reason :The blowing wind does not change the distance between the source and listener which is a must for Doppler effect.

What among the following remains same in case.of thevvaves coming,put from coherent sources?
