If the accelerating voltage is decreased from 35,000 to 30,000 V, determine what will happen to the wavelength of the shortest wavelength X rays produced.

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.

The answer would be a
