Answer:
1. Golf ball is in the range of only particulate detectable range
2, alpha partcle is in ultraviolet range of wavelength
3.bullet is in xray range of wavelength
All in the EMW spectrum
Explanation:
It is given that,
Initial state of electron,
Final state of electron,
The wavelength of the excited electron is given by :
Where
R is Rydberg's constant
or
Let f is the frequency of the observed photon. It is given by :
Hence, this is the required solution.
So, C = kE°A/d
putting the values,
C
= 3.8 × 8.85×10^(-12) × 3.14×1.5×1.5 × 10^(-6)/0.43 × 10^(-3)
so, 1.02 × 10^(-13)
so the most appropriate answer is 2 ...that is
1.4 × 10^(-13) ....answer !!
It will be traveling exactly 24 miles per hour <span />
