Standing waves and transverse waves

[Jiayi_Cao_3E]

Hello! I'm just wondering whether the De Broglie equation can be used for all objects? If I remember correctly it can be used for all objects but are bonded electrons the only exception as they travel in standing waves, according to De Broglie's model? Do all other objects that have a detectable wavelength travel in transverse waves?

I think DeBroglie's wavelength applies to any object as long as it has momentum.

From what I understand, the De Broglie equation can be used for objects that have wavelike properties. If they are too heavy, then they will not be detected. As for the transverse part, objects travel in either transverse or longitudinal which can thus be detected.

Although all matter has wavelike properties, why is it only noticed for moving objects, especially those with small mass. How come the baseball vs light obstruction example depicts this model?
