Advanced photodiode detectors have a second light-emitting diode, operating at a wavelength of 2.0 × 10-7 m, to detect even smaller smoke particles from smoldering flames. what is the frequency difference between the two light beams? a) 12.0 × 10^15 hzb) 3.0 × 10^15 hzc) 2.0 × 10^15 hzd) 1.0 × 10^15 hz

Frequency,

Explanation:

It is given that,

Wavelength of the light- emitting diode,

We need to find the frequency difference between the two light beams. It can be calculated using the following relation as :

So, the frequency difference between the two light beams is . Hence, this is the required solution.

area of focus

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
