Answer:
6.9 × 10²² m
Explanation:
Data Given:
Frequency of wave = 4.34 ₓ 10⁻¹⁵s⁻¹
wavelength = ?
Solution:
Formula used
c = λν
Where
c = speed of light = 3 × 10⁸ ms⁻¹
λ = Wavelength
ν = frequency
As we have to find out wavelength we have to rearrange above equation
λ = c /ν . . . . . . . .(1)
Put values in above equation 1
λ = 3 × 10⁸ ms⁻¹ / 4.34 ₓ 10⁻¹⁵s⁻¹
λ = 6.9 × 10²² m
