Light of wavelength and frequency v passes through a single slit of width ( a ) .The diffraction pattern is observed on a screen a distance from the slit. The above graph clearly indicated that, as the wavelength increases, the energy associated with the particle decreases exponentially. An increase in the energy mismatch of the excitation wavelength and the plasmon resonance leads to a significant decrease in PM-PL. The speed of both the waves is equal v1 = v2 = v, where v is the velocity of a sound wave, The wavelength of the first wave ( 1) =7.5 mm = 7.5 10-3 m, Frequency of the first wave (f1) = 45 kHz = 45 103 Hz, Wavelength of second wave (2) = 100 nm = 100 10-9 m, (7.5 10-3)/(100 10-9) = f2/(45 103), f2 = [(7.5 10-3) (45 103)]/(100 10-9). Carefully hold a metal rod horizontally at its mid-point. The activity Making Mexican waves demonstrates wave energy and wave behaviours. Frequency is the number of crests or troughs that pass a set point in a given amount of time. The phenomenon of it was given by Planck known as Plancks law, E = h. Because the velocity is constant, any increase in frequency results in a subsequent decrease in wavelength. If a wave whose frequency is 45 kHz has a wavelength of 7.5 mm, then find the frequency of the wave whose wavelength . 69908 views The velocity of a wave is equal to the product of its wavelength and frequency.
