1.	How fast is an electron moving if it has a wavelength equal to the distance it travels in one second?
Answer» `SQRT((m)/(h))` `sqrt((h)/(m))` `sqrt((h)/(p))` `sqrt((h)/(2(KE)))` Solution :Distance travelled in 1 sec = velocity (V) Given `LAMDA = v`. HENCE, `lamda = (h)/(mv)` becomes `v = (h)/(mv)` or `v^(2) = (h)/(m) or v = sqrt((h)/(m))`
