Question

Find the length of the smallest standing wave that can be formed with light having frequency 600 THz

Answer 1

`L=2.5*10^-^7m`

Step-by-step explanation:

From the question we are told that

Frequency of light
`f= 600 THz`

Generally the equation for wave is mathematically given as

`\lambda=(c)/(\gamma)`

Where

`1THz=10^1^2`

`\lambda=(3*10^8)/(600*10^1^2)`

`\lambda=0.5*10^-^6m`

Generally the equation for a fundamental Frequency is mathematically given as

`L=(\lambda)/(2)`

`L=(0.5*10^-^6)/(2)`

Therefore the length of the smallest standing wave

`L=2.5*10^-^7m`
