Coherent light that contains two wavelengths 660 um and 4T1] 11m , passes through two narrow slits with a separatiun MD 230 mm and an interference pattern is obsewed an a screen which is a distance 4 9i] mtrom the slits. What is the distance on the screen between the rsteorder bright fringe for each wavelength? Two radio antennas A and B radiate in phase. Antenna B is a distance of 140 m to the right of antenna A. Consider point Q along the extension of the line connecting the antennas, a horizontal distance of 50.0 m to the right of antenna B. The frequency, and What is the longest wavelength for which there will be destructive interference at point Q? hence the wavelength, of the emitted waves can be varied. Express your answer using two significant figures. AEd ? X= m Submit Request Answer Part B What is the longest wavelength for which there will be constructive interference at point Q?
