Interference is in complete agreement to law of conservation of energy

Tilak gurjar posted; “Interference is in complete agreement to law of conservation of energy. Comment” Answer: If there were no interference, the resultant intensity at a point illuminated by two sources will be I = I1+I2 Due to interference This shows that energy is conserved even after interference. There is only a redistribution of energy. There […]
