Prior to the switch to digital television broadcasting, and to the popularity of cable television, many homes had outdoor TV antennas. TV-reception antennas for VHF (channels 2 through 13) were constructed with cross wires supported at their centers, as shown in the figure below. The ideal length for the cross wires is one-half the wavelength to be received, with the more expensive antennas having one for each channel. Suppose you measure the lengths of the wires for channels 6 and 4 and find them to be 0.963 m and 1.213 m long, respectively. What is the frequency for channel 6? Hz What is the frequency for channel 4? Hz

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.
