Answer :
<u>Solution For 1 : </u>
Given,
wavelength =
Speed of light =
Formula used :
.............(1)
= frequency
= wavelength
c = speed of light
Now put all the given values in above formula, we get
=
(1Hz = 1 per second)
Therefore, the frequency of a photon in hertz is .
<u>Solution For 2 : </u>
Given,
Frequency =
Speed of light =
Now put all the given values in above formula (1), we get
Therefore, the wavelength of a wave is 13.38 m.
<u>Solution For 3 : </u>
Given,
wavelength =
Speed of light =
Now put all the given values in above formula (1), we get
=
Therefore, the frequency of a photon in hertz is .
<u>Solution For 4 : </u>
Given,
Frequency =
Speed of light =
Now put all the given values in above formula (1), we get
Therefore, the wavelength of a wave is .
<u>Solution For 5 : </u>
Given,
wavelength = (1 m = 1000 mm)
Speed of light =
Now put all the given values in above formula (1), we get
=
Therefore, the frequency of a photon in hertz is .
