Question

2. Două surse coerente oscileaza cu frecventa de 1 Hz, iar undele generate de elel se propaga pe suprafața apei cu viteza de 1, 5 m/s . Determinați pentru ce valoare minima a diferenței de drum pe suprafața apei se va observa :a) amplitudinea undelor b) atenuarea undelor

Answer 1

the correct answer is B

Step-by-step explanation:

Attenuation We can define the attenuation of a wave as the decrease in its intensity as it moves away from the focus. It is exclusively due to the distribution of its energy over a growing surface. This happens in the aqueous environment or in the water when a wave dissipates.
