What is the wavelength of electromagnetic radiation with a frequency of 8.6 X 1011 Hz?
The relationship between frequency and wavelength is given as:
`lambdanu = c`
i.e. the product of wavelength and frequency is equal to speed of light in vacuum, which is equal to about 3 x 10^8 m/s
Hence, wavelength, `lambda` = `c/nu`
= `3.5xx10^(-4) m`
Hope this helps.
