Question

question 19 (1 point)
de broglie first noted the
particle nature of light
speed of light is 3.00 x 10^8m/s
wave nature of matter
wave nature of light
answers a, b & d are correct

Explanation:

De Broglie proposed the wave - particle duality of matter. He hypothesized that just as light has both wave - like and particle - like properties, matter (such as electrons, protons, etc.) also has wave - like properties. The de Broglie wavelength formula \(\lambda=\frac{h}{p}\) (where \(h\) is Planck's constant and \(p\) is the momentum of the particle) describes the wave nature of matter.

• Option a: The particle nature of light was mainly explored by Einstein (photons) and others.
• Option b: The speed of light being \(3.00\times 10^{8}\ m/s\) is a fundamental constant in physics, but it is not related to de Broglie's main contribution.
• Option d: The wave nature of light was well - known before de Broglie (e.g., from Young's double - slit experiment).

Answer:

wave nature of matter
