Neet 2005 PYQ Free Mock Test

Assertion: The energy ($E$) and momentum ($p$) of a photon are related by $p=E/c$.Reason: The photon behaves like a particle.

Assertion: The clouds in sky generally appear to be whitish.Reason: Diffraction due to clouds is efficient in equal measure at all wavelengths.

Assertion: Television signals are received through sky-wave propagation.Reason: The ionosphere reflects electromagnetic waves of frequencies greater than a certain critical frequency.

Assertion: The logic gate NOT can be built using diode.Reason: The output voltage and the input voltage of the diode have $180^{\circ }$ phase difference.

Assertion: The resolving power of a telescope is more if the diameter of the objective lens is more.Reason: Objective lens of large diameter collects more light.
