The correct answer is: Anti-nodes.
Explanation:
When the interference between the two waves is constructive and the <span>points on the wave that undergo the maximum displacement during each vibrational cycle </span><span>of the standing wave </span>back and forth. Those points are called anti-nodes. Hence, in the case of sound waves, interference creates standing waves, and the points on the medium that move up and down with the highest amplitudes are called anti-nodes.
The answer is going to be A
Answer:
The bulb consumes electrical energy at the rate of 500 Watts
1 Watt = 1 Joule/sec where the joule is the unit of energy
Electric energy is often expressed in kw-hrs
This means that 1 kilowatt of power is used for 1 hour
1 kw-hr = 1000 joules/sec * 3600 sec = 3.6E6 joules of energy
