Name the high energetic invisible electromagnetic waves which help in the study of the structure of crystals
What is the range of the wavelength of the following electromagnetic waves?
(a) Infrared.
State the approximate range of wavelength associated with infrared rays.
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,
50% of the X-ray coming from a Coolidge tube is able to pass through a 0.1 mm thick aluminium foil. The potential difference between the target and the filament is increased. The thickness of the aluminium foil that will allow 50% of the X-ray to pass through will be
Cutoff wavelength of X-rays coming from a Coolidge tube depends on the
(a) target material
(b) accelerating voltage
(c) separation between the target and the filament
(d) temperature of the filament.
State two properties of infrared radiations which differ from visible light.
The frequency of x-rays, y-rays and ultraviolet rays are respectively a, b and c. Then:-
Which part of the electromagnetic spectrum can the human eye detect?
How do ultraviolet rays compare with visible light?
