Question

Calculate the frequency of a wave with a wavelength of 5.62 x 1010 m. (first convert m to nm)

Answer 1

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
