Two objects are moving at the same speed. which (if any) of the following statements about them are true? check all that apply. the de broglie wavelength of the heavier object is longer than that of the lighter one. if one object has twice as much mass as the other, its wavelength is one-half the wavelength of the other. doubling the mass of one of the objects will have the same effect on its wavelength as does doubling its speed.
