It is determined that a certain wave of infrared light has a wavelength of 8.45 mm
c=2.99 x 108 m/s, what is the frequency of this infrared wave? (Round your an
figures.)

3.54 x 10^10Hz

Explanation:

Given that:

wavelength = 8.45 mm

Since unit of wavelength is metres, convert 8.45 millimeters to metres

(If 1000mm = 1m

8.45mm = 8.45/1000 = 8.45 x 10^-3m)

Wave speed (c) = 2.99 x 10^8 m/s

Frequency of the infrared wave = ?

Now apply the formula

wavespeed = frequency x wavelength

i.e C = F λ

Where F = C / λ

F = 2.99 x 10^8 m/s / 8.45 x 10^-3m

F = 3.54 x 10^10Hz

Thus, the frequency of this infrared wave is

3.54 x 10^10 Hertz

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

the product of the pressure and volume is also constant
