RADIATION PART 2

Radiation Part 1

When Some Part Of Radiation Is Absorbed And Remaining Part Is Reflected

Assertion: CO_(2) present in the atmosphere absorbs heat radiated from heat radiated from earth in the form of IR radiations. Reason: CO_(2) is a pollutant.

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

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

Assertion : CO_2 and methane are called greenhouse gases. Reason : These - radiate heat and radiations cause global warming.

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

Electromagnetic radiations with wavelength: gamma_2 are used in TV communication systems. Identify and name the part of e.m. spectrum to which these radiations belong.
