Located adjacent to red on the electromagnetic spectrum, and having a longer wavelength, is radiation, which we cannot see but which we can detect as heat. this is an important wavelength for the greenhouse effect, because its wavelength is blocked by greenhouse gases.

infrared radiation

Explanation:

infrared radiation - infrared radiation is part of electromagnetic radiation which wavelength range from about 700 nano meters (nm) to 1 millimeter (mm).

Infrared radiation is invisible to  naked eye,  however it can be felt as heat for longer duration infrared waves. Any type of radiation — whether it is  visible light or radio waves — may possibly be hazardous if extremely focused in a high-powered narrow beam

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

the ima (higher than 1m) will be greater than the ima with the height of 1m.
