Calculate the de Broglie wavelength of a 4.5-MeV α particle. Explain if a relativistic or non-relativistic approach is required

4.4x10^-32m

Explanation:

Using

Wavelength = hc/E

= 6.63*10^-34 * 3x10^8/ 4.5 x10^ 6ev

= 4.4*10^-32m

Yes a relativistic approach is used because the particle moves at the speed of light

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
