To solve this problem, we will get f and then we will use it to calculate the power.
So, for this farsighted person,
do = 25 cm and di = -80
Therefore:
1/f = (1/25) + (1/-80) = 0.00275 = 0.275 m
Power = 1/f = 1/0.275 = +3.6363 Diopeters.
This means that the lens is converging.

Answer:
The tunnel probability for 0.5 nm and 1.00 nm are
and
respectively.
Explanation:
Given that,
Energy E = 2 eV
Barrier V₀= 5.0 eV
Width = 1.00 nm
We need to calculate the value of 
Using formula of 

Put the value into the formula


(a). We need to calculate the tunnel probability for width 0.5 nm
Using formula of tunnel barrier

Put the value into the formula


(b). We need to calculate the tunnel probability for width 1.00 nm


Hence, The tunnel probability for 0.5 nm and 1.00 nm are
and
respectively.
