What is the wavelength of the light emitted that has a frequency of 1.50 x 1013 hz? 2.5 x 10-21 m 2.0 x 10-5 m 5.0 x 105 m 4.5 x 1021 m

Answer : The frequency of the light is,

Explanation : Given,

Frequency of the light =

Formula used :

where,

= frequency of light  =

= wavelength of light  = ?

c = speed of light =

Now put all the given values in the above formula, we get the wavelength of the light.

Therefore, the frequency of the light is,

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
