23. Two mirrors of a laser separated by 8.0 cm form an optical cavity in which standing waves of laser light can be set up. Each standing wave has an integral number n of half wavelengths in the 8.0 cm length, where n is large and the waves differ slightly in wavelength. Near 1 = 533 nm, determine the difference in wavelength between adjacent standing waves i.e., the least difference in wavelength between any two standing waves about that wavelength. Ans. 1.8 pm
