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 
Answer:
Mass = 0.139 kg
Explanation:
There is a formula in terms of force, acceleration and mass which is:
Force = mass × acceleration
Put the values into the formula.
5 = m × 36
m = 5 ÷ 36
<u>m = 0.139 kg</u>
