uses of infrared radiationUsed in night vision devices to observe animals or people using the phenomenon called infrared illumination. The observant will not know that they are being observed.Used in astronomy to observe objects that are blurred and hidden by the interstellar dust. Infrared imaging process is used here.Used in astronomical telescopes that are equipped with infrared sensors and these telescopes are used to detect distant planets that are in the dusty regions of space, as they cannot be viewed using a normal telescope. They are also used to detect objects that have had a high red-shift (shifting of wavelength towards the red end of the spectrum).Used in infrared lamps (lamps that emit infrared radiation) and these lamps are used for drying paint, wallpapers and printing inks, to keep food warm, in heaters that are used during cold weather and in heat treatments in the field of medicineUsed in infrared lasers that produce infrared beams that can be used to read information on compact discs.Used in Infrared imaging devices that are used to obtain images of infrared radiation that are reflected or produced by objects, for example, heat insulation in buildings, sources of thermal pollution, mapping vegetation on the earth’s surface.Used in the chemical industry to determine molecular structure and composition of substances by studying their infrared emission or absorption.

Answer from: Quest

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:

A150 w lamp emits light of wavelength 590 nm uniformly in all directions. what is the photon flux (photons per unit area per unit time) on a small screen at a distance 2.3 m from the lamp? assume the photons are uniformly distributed over the surface of a sphere of radius 2.3 m.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
