If light can be both particles and waves, then this implies that matter can be both waves and particles too. The wavelength of matter waves can be calculated by the equation wavelength = h/p. Where h is Planck's Constant and p is momentum. However, because of this equation most material objects cannot be measured.

The statement is incorrect. The wavelength of matter waves can indeed be calculated using the equation wavelength = h/p, where h is Planck's constant and p is momentum. However, it does not imply that most material objects cannot be measured.
According to quantum mechanics, all particles, including matter particles like electrons and atoms, can exhibit wave-particle duality. This means that they can behave like both particles and waves under certain conditions. The wavelength associated with matter particles is called the de Broglie wavelength.
The equation wavelength = h/p is known as the de Broglie wavelength equation. It relates the wavelength (λ) of a matter wave to the momentum (p) of the particle and Planck's constant (h). This equation tells us that as the momentum increases, the wavelength decreases, and vice versa.
Although it may be challenging to directly measure the wavelength of larger, macroscopic objects due to their high momentum and correspondingly small wavelengths, it does not mean that they cannot be measured at all. In practice, the wave-like behavior of macroscopic objects is usually not observable due to their tiny wavelengths. However, the equation still holds true, and the wave-particle duality phenomenon has been experimentally verified for tiny particles like electrons.
