Formulas related to wavelength 'w' 💭w = v/f 💭w = 1/wave number 💭w1 = 2l (when pipe is opened at both ends) 💭w1 = 4l (when pipe is opened at one end) 💭Delta w = Us/f (doppler shift) Wavelength for obs. = w - delta w = v/f - Us/f 💭w = hc/Ve 💭w = hc/E 💭w = h/mv 💭w = h/P as P = underroot 2mE so 💭w = h/underroot 2mE (de Broglie wavelength) 💭w = underroot 150/V A° (short method for de Broglie wavelength. This formula is applicable only for e-) 💭1/w = RH (1/p²-1/n²) 💭Wmaxi/Wmini = n²/n²-p² (for determining ratio b/w maxi. Wavelength to mini. Wavelength for series of atomic spectrum) 💭w = 2pir/n (n is no. of loops in a circle) 💭h/mv = 2pir
