10) From the options provided for this question, gamma particle is the most energetic. Recall that gamma rays are high energy electromagnetic radiation which are capable of causing a high degree of ionization in matter.
11) The bombardment of U-235 with neutrons leads to the reaction;
Hence
a = 92, b= 95, c= 53
12) In positron emission, a proton is transformed into a neutron. The mass number of the daughter nucleus is the same as its parent but the atomic number decreases by 1.
Hence;
Answer :
(a) The energy of blue light (in eV) is 2.77 eV
(b) The wavelength of blue light is
Explanation:
The relation between the energy and frequency is:
where,
h = Plank's constant =
Given :
Frequency =
Conversion used :
So,
Also,
So,
The energy of blue light (in eV) is 2.77 eV
The relation between frequency and wavelength is shown below as:
Where,
c = the speed of light =
Frequency =
So, Wavelength is:
Conversion used :
The wavelength of blue light is
