Answer:
f = 0.534×10⁻² Hz
Explanation:
Given data:
Frequency of wave= ?
Wavelength of wave = 5.62×10¹⁰ m
Solution:
Formula:
Speed of wave = wavelength × frequency
Speed of wave = 3×10¹⁷ nm/s
λ = 5.62×10¹⁰m×10⁹ nm/1 m = 5.62×10¹⁹ nm
Now we will put the values in formula.
3×10¹⁷ nm/s = 5.62×10¹⁹ nm × f
f = 3×10¹⁷ nm/s / 5.62×10¹⁹ nm
f = 0.534×10⁻² s⁻¹ or
f = 0.534×10⁻² Hz
