Physics 11.2.3b - Snell's Law Example

Snell's Law. An example problem is set up and explained.

I kept forgetting to cancel out the sin with sin^1- and would get the wrong answer, this was a really helpful and clear video, thankyou!

Once we find the sine of the angle, we have to use inverse sine to find the angle. In other words, the goal is usually to find the angle, and Snell's Law just gives us the sine of the angle, so we then use inverse sine to find the angle.

Hope that helps,
D.O.

@mhmcupcakes That is certainly possible. There are many different types of glass.

Thanks very much :), its kinda hard to do physics through distance education (at home) without some verbal help!

[masterchief]

thanks man, u explain it really well :)

[juliocesaraguilera]

when are you ever going to use this in your daily life

[fraddi]

why is it sin and not cos or tan for that matter in this eq'n? thanks!

[sharon]

you said .5579 but you type .5597 :p hahaha lol anyway thanks for the helpful teaching :)

[froilanpama]

my answer is not an angle. lol. i dont know much how to use a scientific calculator

at 2:45 u said ".5579 " but u wrote . 5597 :S correct that
