acctualy normal on the wave front called RAY, in the beta
radiation there is wave packet and hence no wave frant. in
cathod ray there is electromegnatic radiation and we can
use word ray but in the case of beta partical we use word
beta radiation insted of betaray

A bullet of mass m travelling at velocity v has a kinetic energy of ½mv2 when it strikes a ballistic pendulum of mass 1000 grams. The kinetic energy of the two masses moving together just after the moment of impact is about a thousand times smaller than ½mv2. What has most of the bullets initial kinetic energy been converted to?
