Q.True regarding x ray
a. x-rays travel in straight lines
b. x- rays are emitted in all directions from the target of
the x- ray tube
c. x- rays obeys the physical law of light
d. x- ray follows square law
e. Square law usefuless in portable x- ray equipment
Q.abc---X- rays obeys the physical law of light.X- ray follows inverse square law( the intensity
of x ray falling on flat surface from a point source is inversely proportional
to the square of the distance from the point source.).The concept of inverse
square law is useful in portable x ray equipment . [Chapter 15, 4th edition ,1990 reprinted 2010 , Christensen’s Physics of
