  • Question 9/10
    4 / -1

    Infrared lamps are used in restaurant to kept the food warm. The infrared radiation is strongly absorbed by water, raising its temperature and that of the food. An infrared lamp used in a restaurant emits monochromatic light of wavelength 1240 nm.

    If the power of lamp is 100 W, then the number of photons emitted per sec is –

    Solutions

     

  • Question 10/10
    4 / -1

    Infrared lamps are used in restaurant to kept the food warm. The infrared radiation is strongly absorbed by water, raising its temperature and that of the food. An infrared lamp used in a restaurant emits monochromatic light of wavelength 1240 nm.

    If the radiations of the same lamp are falling on a metal surface (work function = 2eV) and the quantum yield is 0.2. The number of ejected electron from the surface in 1 minute is –

    Solutions

    Since energy of falling photons is less than work function of metal surface, so ejection of electrons will not occur.
