Conduct Research (15 points) Evaluate claims about the effects that different frequencies of electromagnetic radiation have when absorbed by matter. 1. Conduct research to identify claims made about the effects that certain frequencies of EMR have when absorbed by matter. Find two examples from published sources. Write brief descriptions of your two examples. (5 points)

A) What parts of the EM spectrum are being used? Compare them in terms of wavelength, frequency, and energy.​

a. are

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
