Calculate the wavelength of electromagnetic wave having frequency `5 xx 10^(16)` Hz in free space.

Explanation

To calculate the wavelength of an electromagnetic wave with a given frequency, we can use the formula that relates the speed of light (c), frequency (ν), and wavelength (λ):

\[ c = ν \cdot λ \]

Where:
- \( c \) is the speed of light in a vacuum, approximately \( 3 \times 10^8 \) meters per second.
- \( ν \) is the frequency of the wave.
- \( λ \) is the wavelength of the wave.
