Answer:

The wavelength is 7.0x10⁻⁴⁷ m

Explanation:

To solve this problem we can use the equation:

c = λ*v

Where:

c is the speed of light (3x10⁸m/s)

λ is the wavelenght (in m)

v is the frequency (in Hz)

We put the data given by the problem:

3x10⁸ m/s = λ * 4.3x10⁵⁴ Hz

And solve for λ:

λ = 7.0x10⁻⁴⁷ m
