4. If index of refraction 1 is 1.5, index of refraction 2 is 2.0, and the angle of incidence is 45 degrees, what is the angle of refraction?

15 index ofreaction 21820 and the angle of medence is as degres what's the angle of reaction

16 degrees

32 degrees

48 degrees

64 degrees

The angle of refraction is 32.0 degrees

Snell’s Law describes how a ray of light will change direction as it passes from one medium into another, or as it is reflected from the interface between two media.

Snell's law states that:

where;

Using the formula above

1.5 * sin 45 = 2.0 * sin r

sinr = 1.5 × sin 45/2

r = 32.0 degrees

Therefore, the angle of refraction is 32.0 degrees

The angle of refraction is 32°

Explanation:

By snell law, we have that:

n₁*sen(θ₁) = n₂*sen(θ₂)

Where n₁ = 1.5

n₂ = 2.0

θ₁ = 45°.

then we want to find the angle of refraction.

1.5*sin(45°) = 2*sin(x)

x = Asin(1.5*sin(45°)/2) = 32°

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

the answer is b.) hydrogen bonds between bases.
