People with bad eyesight use glasses made of high index glass. If a ray in air strikes the glasses at 31.2 deg, and enters the glass at 17.6 deg, what is the index of refraction of the glass?

Refractive index of the glass is 1.71

Explanation:

As we know that when light enter from one medium to other medium then due to refractive index change light bends away or towards the normal

This phenomenon is known as refraction of light and as per Snell's law we have

so we have

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
