Assertion: X-ray astronomy is possible only from satellites orbiting the earth.
Reasion: Efficiency of X-rays telescope is large as compared to any other telescope.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
C
The earth’s atmosphere is transparent to visible light and radio waves but absorbs X-rays. Therefore, X-rays telescope cannot be used on earth surface.

optical and radio telecopes are build on ground but X-ray astronomy is possible only from satellites or biting the earth. Explain why?

Assertion : X-rays show the phenomenon of photoelectric effect. Reason : The energy of X-ray photon is quite large.

Assertion: It is possible to transmit signals from one place on the earth to practically other place on earth. Reason: A geostationary satellite orbiting the earth is u sed for transmission.

The period of revolution of a satellite orbiting Earth at a height 4R above the surface of Warth is x hrs, where R is the radius of earth. The period of another satellite at a height 1.5R from the surface of the Earth is

Assertion : Intensity of X - rays can be controlled by adjusting the filament current and voltage. Reason : The intensity of X - ray photons emitted per second from the target.

It is teming to think that all possible transituion are permissible and that an atomic spectrum series from the transition of an electron from any intial orbital to any other .However this is not so because a photon a photon has as intrinsic spin angular momentum of sqrt(2) h// 2pi corresponding to S = 1 although it has no charge and no rest mass On the other hand , an electron has got two typwe of agular momentum orbit angular momentum L = [sqrt(l(l+1))] h//2pi ,and spin angular momentum L_(1) = sqrt(s(s + 1)) h//2pi arising from orbital motion and spin motion of the electronn during any electton transition must compentum for the angular momentum carried away by the photon .To salary this condition the different between the azisition quantum number of teh orbital witjhin which the transition (l = 2) cannot make a transition into as x-orbital (l = 0) because the photon cannot carry away enough angular momentum Electron transition from 4s to 3s orbital is forbiddeon meating that it cannot because
