Energy of our sun. It composed of a lot of hydrogen and by the two fusion of isotopes. Helium is then released.
Answer:
Explanation:
Frequency is mathematically defined as the quotient of speed divided by wavelength.
where
v-is the speed of light
-w is wavelength.
Given the speed of the wave as and the wavelength , we substitute these values in the Frequency function to solve for frequency:
Hence, the wave's frequency is
We see that around us there are many things that makes use of circuits to make our lives easier Circuits are used to convert electrical energy to other forms of energy. For instance, a heater contains circuits which converts the electrical energy into heat. A circuit in a fan converts the electrical energy into motion. In a doorbell, the circuits are used to convert electrical energy into sound.<span />
Answer:
0.3376 mm
Explanation:
The computation of the spacing in mm between the slits is shown below:
As we know that
where,
= wavelength
L = distance from the scrren
= spanning distance
As there are 11 bright fingers seen so m would be
= 11 - 1
= 10
Now placing these values to the above formula
So, the spacing is
= 0.3376 mm
We simply applied the above formula.
Answer:
This represents radiation in ultra-violet region .
Explanation:
Energy of the orbit where n = 3 is given as follows
= -1.511 eV
Energy of the orbit where n = 1 is given as follows
= 13.6 eV
Difference of [tex]E_3 and [tex]E_1 = - 1.511+ 13.6
= 12.089 eV.
The wavelength of light having this energy in nm is given by the expression as follows
Wavelength in nm = 1244 / energy in eV
= 1244 / 12.089
= 102.90 nm
This represents radiation in ultra-violet region .
