Question

which formula represents snells law?
○ ( n _ { 1 } + sin \theta _ { 1 } = n _ { 2 } + sin \theta _ { 2 } )
○ ( n _ { 1 } sin \theta _ { 1 } = n _ { 2 } sin \theta _ { 2 } )
○ ( n _ { 1 } cos \theta _ { 1 } = n _ { 2 } cos \theta _ { 2 } )
○ ( n _ { 1 } + cos \theta _ { 1 } = n _ { 2 } + cos \theta _ { 2 } )

Explanation:

Step1: Recall Snell's law concept

Snell's law is about refraction of light.

Step2: State the formula

It states \(n_1\sin\theta_1 = n_2\sin\theta_2\), where \(n_1\) and \(n_2\) are refractive indices of two media, \(\theta_1\) is the angle of incidence, \(\theta_2\) is the angle of refraction.

Answer:

\(n_1\sin\theta_1 = n_2\sin\theta_2\)
