3(n-6)+4

difference of n and 6=n-6

multiply by three=3(n-6)

add 4=3(n-6)+4

n-6 is in parenthesis because the difference of n and 6 comes before multiplying by 3.

If light travels at 3. 108 m/s and its frequency is 6. 1015 Hz, then its wavelength is:

Sergio039 [100]

Answer:

$5 * 10^{-8} m$

Step-by-step explanation:

The speed of light is $3 * 10^8 m/s$ and its frequency is $6 * 10^{15} Hz$ .

The speed of light is given as:

c = λ * f

where λ = wavelength of light

f = frequency of light

Therefore, the wavelength is given as:

λ = c / f

=> λ = $\frac{3 * 10^8}{6 * 10^{15}}$

=> λ = $5 * 10^{-8} m$

The wavelength of the light is $5 * 10^{-8} m$
