Question #d02ff

Answer 1

`6 xx10^14 Hz`

Explanation:

`flamda=c`
`f=c/lamda= (3xx10^8m/s)/(500xx10^-9)=6 xx10^14 Hz`

Answer 2

`6.67xx10^14Hz`

Explanation:

Wavelength formula is `C=λf` or `λ=C/f` or `f = C/λ`,
so Frequency = Velocity divided by wavelength, where
`C` is the velocity, which is the speed of light: `3.00 × 10^8 m/sec`
`λ` is the wavelength in meters
`f` is the frequency in Hertz (cycles per second)
`f = 3.00 × 10^8 m/sec /4.5 xx 10^(-7) m = 6.67xx10^14Hz`
