Wave Nature Of Light Of Matter (de-Broglie)
Dual nature of radiation and Matter

142537 Light appears to travel in straight line because

1 its velocity is very large
2 its wavelength is very small
3 it is formed of corpuscles
4 its frequency is very small
Dual nature of radiation and Matter

142388 Given below are two statement: One is labelled as Assertion $A$ and the other is labelled as Reason $\mathbf{R}$
Assertion A: The beam of electrons show wave nature and exhibit interference and diffraction. Reason R: Davisson Germer Experimentally verified the wave nature of electrons.
In the light of the above statements, choose the most appropriate answer from the options given below:

1 A is correct but R is not correct
2 Both $\mathrm{A}$ and $\mathrm{R}$ are correct but $\mathrm{R}$ is not the correct explanation of $\mathrm{A}$
3 Both $\mathrm{A}$ and $\mathrm{R}$ are correct and $\mathrm{R}$ is the correct explanation of $\mathrm{A}$
4 A is not correct but R is correct
