    In a single slit diffraction experiment, for wavelength 'λ\lambda', half angular width of the principal maxima is 'θ\theta'. Also for wavelength of light 'pλp\lambda', the half angular width of the principal maxima is 'qθq\theta'. The ratio of the half angular widths of the first secondary maxima in the first case to second case will be

    Kinetic Theory of Gases. Asked 2 times: 15 Apr 2026 S2, 16 Apr 2026 S2 See all 2 times it was asked

    115
    The average transnational kinetic energy of a molecule in a gas is E1E_1. The kinetic energy of the electron (e) accelerated from rest through potential difference 'V' volt is E2E_2. The temperature at which E1=E2E_1 = E_2 possible is (mass of molecule and electron is same) (N = number of molecules, V = Velocity, R = gas constant)
