Students have asked these similar questions
true or false
a. Caffeine absorbs light along the visible region of the electromagnetic spectrum.
True
False
a. Particles of light emit or absorb energy with surrounding molecules. This phenomenon is governed by the Law of Conservation of Energy.
True
False
When light hits an object, the object absorbs some of the light and reflects the rest of it. The wavelengths that are reflected determine how our eye perceives the color. Why does the human eye perceive a red colored dress as the color red?
a)The moeclues of the dress do not absorb red light wavelengths.
b)A red dress will primarily absorb red light wavelengths.
c)The molecules of the dress absorb green and blue light wavelengths.
d)A red dress will not absorb light wavelengths from non-red colors.
The correct arrangement of figure I is:
light source → photomultiplier tube → sample → monochromator
light source → sample → monochromator → photomultiplier tube
light source → monochromator → sample → photomultiplier tube
light source → sample → photomultiplier tube → monochromator
