Answer:
6) λ = 0.84 × 10⁻⁸ m
7) λ = 0.84 × 10⁻⁶ m
Explanation:
6) Given data:
Wavelength of photon = ?
Frequency of photon = 3.56 × 10¹⁶ Hz
Solution:
Formula:
Speed of radiation = frequency × wavelength
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 3.56 × 10¹⁶ Hz × λ
λ = 3×10⁸ m/s / 3.56 × 10¹⁶ s⁻¹
λ = 0.84 × 10⁻⁸ m
7) Given data:
Wavelength of photon = ?
Frequency of photon = 6.15 × 10¹⁴ Hz
Solution:
Formula:
Speed of radiation = frequency × wavelength
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 6.15 × 10¹⁴ Hz × λ
λ = 3×10⁸ m/s / 6.15 × 10¹⁴ Hz s⁻¹
λ = 0.84 × 10⁻⁶ m

Explanation:
when you get addicted to it and won't stop taking it
Answer:
The concentration of the resulting solution is 0.25 or one quarter of the standard solution
Explanation:
Whereby the molar concentration of the standard solution is P molar per liter, we have
25 ml of the standard solution contains
25/1000×P moles of the standard solution such that the resultant solution has a volume of 25 + 75 = 100 ml contains 0.025 P moles of the standard solution
The concentration of a solution is the number of moles contained per liter, which gives
100 ml contains 0.025 P moles
1 liter = 1000 ml will contain 1000/100 × 0.025 = 0.25 P moles of the stanard solution
Therefore, the concentration of the resulting solution is 0.25 or one quarter of the standard solution.
