Drawbacks of Rutherford Atomic Model

Why are light rays known as electromagnetic waves? 

Write the drawbacks of Rutherford's atomic model.

 An object emits two different radiation, when it absorbs certain amount of energy having  $2400 \stackrel{\mathrm{o}}{\mathrm{A}}$ of wavelength in which one radiation having $6000 \stackrel{\mathrm{o}}{\mathrm{A}}.$ What is the wavelength of other radiation?

Which value is closest to the wavelength, in meters, for a quantum of light with a frequency of  $8\times {10}^{16}$ per second?

[Given: $\mathrm{c}=3 \mathrm{x} {10}^8 {\mathrm{ms}}^{-1}, \mathrm{h}=6.63 \mathrm{x} {10}^{-34} \mathrm{J}.\sec$]

Two electrons, each moving with a velocity of ${10}^6 \mathrm{m}/{\mathrm{s}}^{-1}$ towards each other. The closest distance of approach between them is $\mathrm{y}\times {10}^{-10} \mathrm{m}.$ Find value of $\mathrm{y}.$

Which of the following radiations has the highest wave number ?

The frequency of yellow light having wavelength $600\mathrm{ }\mathrm{n}\mathrm{m}$ is-

Rutherford scattering formula fails for minimal scattering angles because
