Answer:
λ = 0.029×10² m
f = 0.57×10¹⁷ s⁻¹
Explanation:
Given data:
Wavelength of wave = ?
Frequency of wave = 102.7×10⁶ s⁻¹
Solution:
Formula:
Speed of wave = Wavelength × Frequency
speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = λ × 102.7×10⁶ s⁻¹
λ = 3×10⁸ m/s / 102.7×10⁶ s⁻¹
λ = 0.029×10² m
2nd)
Given data:
Wavelength of wave = 5.267 nm (5.267×10⁻⁹ m)
Frequency of wave = ?
Solution:
Formula:
Speed of wave = Wavelength × Frequency
speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 5.267×10⁻⁹ m × f
f = 3×10⁸ m/s / 5.267×10⁻⁹ m
f = 0.57×10¹⁷ s⁻¹
