Neon gas is generally used in the sign b | Class 11 Chemistry Chapter Structure of Atom, Structure of Atom NCERT Solutions

Question:

Neon gas is generally used in the sign boards. If it emits strongly at 616 nm, calculate

(a) the frequency of emission,

(b) distance traveled by this radiation in 30 s

(d) number of quanta present if it produces 2 J of energy.

Answer:

λ = 616nm or = 616x10^-9m

a) Frequency , v=c/ λ = 3.8x10⁸/ 616x10^-9 = 4.87x10¹⁴ s^-1

b) Velocity of the radiation = 3x10⁸m/s

Therefore distance travelled in 30s = 30x3x10⁸ = 9.0x10⁹m

c) E = hv = hc/ λ = (6.626x10^-34)(3.0x10⁸) / (616x10^-9 ) = 32.27x10^-20J

d) No of quanta in 2J of energy = 2/32.27 x 10^-28 = 6.2x10¹⁸
