Questions|Radiation|Prevost Theory Of Exchange|Absorption ,Reflection & Emission Of Radiation

Assertion : If U.V radiations and infrared radiations fall on a metal plate, stopping potential would be grater for infrared radiations. Reason : Maximum kinetic energy of photoelectrons is inversely proportional to the frequency of incident radiation.

Which radiations causes DNA damgage leading to neoplasitc trnsformations ? (a) Ionising radiations (b) X-rays (c) Non-ionising radiations (d) UV-rays

Assertion(A): The energy of ultraviolet radiation is greater than the energy of infrared radiation Reason (R): The velocity of ultraviolet radition is greater than the velocity of infrared radiation.

Radiation Part 1

Radiation: Stefan's law | Emissive power | Absorptive power | Kirchhoff's law | Spectral emissive power (blackbody radiation curve) | Wein's law Newton's law of cooling: exact and approximate method

Assertion: Like light radiation, thermal radiations are also electromagnetic radiation. Reason: The thermal radiations require no medium for propagatio.

Radiations which are trapped in green house are ___ radiations.

UV radiation and IR radiation have the range
