In quantum mechanics, particles such as electrons and photons exhibit both wave-like and particle-like properties—a concept known as wave-particle duality. Matter waves refer to the wave aspect of this duality.

<caption>Matter Waves - Remark - Just as light can behave like both waves and individual particles, matter (ex. electrons) can also exhibit wave like behaviour under certain coditions. <caption>

Physicist Louis de Broglie introduced the idea in 1924 that particles have their associated wavelengths. Physicist Louis de Broglie introduced the idea in 1924 that particles have their associated wavelengths.
