CHXI02:STRUCTURE OF ATOM

307656 Assertion :
Electromagnetic radiations around \(10^{15} \mathrm{~Hz}\) are called visible light.
Reason :
This is the only part of electromagnetic radiation which is visible to eyes.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
CHXI02:STRUCTURE OF ATOM

307657 A gas absorbs photon of 355 nm and emits at two wavelengths. If one of the emission is at 680 nm, the other is at

1 \({\rm{1035}}\,{\rm{nm}}\)
2 \({\rm{325}}\,{\rm{nm}}\)
3 \({\rm{743}}\,{\rm{nm}}\)
4 \({\rm{518}}\,{\rm{nm}}\)
CHXI02:STRUCTURE OF ATOM

307658 A particular electromagnetic radiation with wavelength 200 nm

1 Has a higher frequency than radiation with wavelength 400 nm
2 Is in the visible region of the electromagnetic spectrum
3 Has a greater speed in vacuum than does radiation of wavelength 400 nm
4 Has a greater energy content per photon than does radiation with wavelength 100 nm
CHXI02:STRUCTURE OF ATOM

307408 Consider the following statements:
I. The energy of electrons in atoms is quantised.
II. The existence of quantised electronic energy levels is a direct result of the wave like properties of electrons.
III. The path of an electron in an atom can never be determined accurately.
The correct statements are

1 I and II
2 II and III
3 I and III
4 All of these
