X can probably be vacuum through space through air and or solid objects
Answer:
32.66 m/s
Explanation:
The potential energy stored in the spring will impart kinetic energy into the dart:
substitute the values:
Answer:
at n= 3 λ = 656 nm
at n= 2 λ = 121.58 nm
Explanation:
Given details
transition of hydrogen atom from n = 2 to n = 3 state
Difference in energy between n = 3 state and n = 2 state :
so, energy of photon is given as
So solve for wavelength
so, λ
=
= 656 nm
for second transition,
energy transmitted is given asΔE
and it is calculated as
E = 1.635*10-18 J solving for wavelength in ENERGY equation we get
so, m
= 121.58 nm
