5. A mobile receiver is receiving signals from two radio transmitters. The mobile receiver is currently placed at a distance of 450m and 150m from the transmitters. The car is now receiving the best network, what is the maximum wavelength of the radio wave transmitter. If the mobile receiver is moving at a distance of 17m/s perpendicular to the transmitters the reception is becoming poor and what is the distance travelled by the mobile when the network is completely lost.

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
