Step 1

To find the frequency of UV radiation with a wavelength of 158 nm, we can use the formula: Frequency (f) = Speed of light (c) / Wavelength (λ) Where c = 3 * 10^8 m/s and λ = 158 * 10^-9 m. f = (3 * 10^8) / (158 * 10^-9) f = 1.898 * 10^15 Hz So the frequency of Show more…

00:01 Hello students for the first part of this question we have to find out the frequency energy is equal to hc divided by lambda where h is the plank constant and lambda is the wavelength c is the speed of light it is in turn equal to plank's constant multiplied by frequency so we can see that the frequency comes out to be speed of light divided by the wavelength.

00:35 Speed of light is taken as 3 into 10 to the power 8 meter per second and the wavelength is 158 .1 nanometer which can be converted into meter via this method.

00:59 The frequency of the wavelength 158 .1 nanometer comes to the frequency of the wavelength 158 .1 nanometer comes out to be 1 .89 into 10 to the par 15 hertz.

01:16 In the next part frequency have been given and we have to find out the wavelength.

01:22 Wavelength can be find out by the ratio of speed of light and frequency.

01:31 The speed of light is 3 into 10 to the power 8 meter per second and the the frequency is 3 .185 into 10 to the par 14 hertz.

01:48 After calculations, the wavelength comes out to be 942 nanometer.

01:58 In the next part, we have to find out the energy.

02:02 The energy can be used in this relation with lambda, which is the wavelength.

02:11 The value of planck's constant is 6 .64 into 10 to the power minus 34.

02:20 The speed of light is 3 into 10 to the power 8 meter per second and the wavelength is 464 .1 nanometer which can be written as 10 to the power minus 9 meters...
