The small ozone layer on top of the stratosphere is crucial for human survival. Why?


Name two sources, each of infrared radiations and ultraviolet radiations.


Frequencies of Kα X-rays of different materials are measured. Which one of the graphs in the figure may represent the relation between the frequency v and the atomic number ?


The figure shows the intensity-wavelength relations of X-rays coming from two different Coolidge tubes. The solid curve represents the relation for the tube A in which the potential difference between the target and the filament is VA and the atomic number of the target material is ZA. These quantities are VB and ZB for the other tube. Then,


The stopping potential in a photoelectric experiment is linearly related to the inverse of the wavelength (1/λ) of the light falling on the cathode. The potential difference applied across an X-ray tube is linearly related to the inverse of the cutoff wavelength (1/λ) of the X-ray emitted. Show that the slopes of the lines in the two cases are equal and find its value.

(Use Planck constant h = 6.63 × 10-34 Js= 4.14 × 10-15 eVs, speed of light c = 3 × 108 m/s.)


Answer briefly.

Give two uses of ultraviolet rays.


If the Earth did not have atmosphere, would its average surface temperature be higher or lower than what it is now? Explain.


Electromagnetic waves with wavelength

  1. λ1 is used in satellite communication.
  2. λ2 is used to kill germs in water purifies.
  3. λ3 is used to detect leakage of oil in underground pipelines.
  4. λ4 is used to improve visibility in runways during fog and mist conditions.
  1. Identify and name the part of electromagnetic spectrum to which these radiations belong.
  2. Arrange these wavelengths in ascending order of their magnitude.
  3. Write one more application of each.

Assertion (A): Ultraviolet radiations is scattered more as compared to the microwave radiations.

Reason (R): Wavelength of ultraviolet radiation is more than the wavelength of microwave radiation.


Name one radiation having the wavelength longer than the wavelength of these radiations.
