A ray of light incident in air strikes a rectangular glass block of refractive index 1.5 at angle of incidence of 45.
Gwar [14]

Refraction is said to occur when there is a change in the speed of light.

<h3>What is the angle of refraction?</h3>

We know that refraction is said to occur when there is a change in the speed of light as it travels form one medium to another.

Given that the refractive index of the rectangular glass block is  1.5. The angle of refraction can be obtained by the use of the Snell's law;

n = sin i /sinr

n = refractive index

sini = angle of incidence

sin r = angle of refraction

sinr = sini/n

sinr = sin 45/1.5

= 0.471

r = 28 degrees

b) Now;

sinr =sin  45/1.2

sinr = 0.589

r = 36 degrees

For the glass

sinr = sin 36/1.5

sin r = 0.392

r = 23 degrees

In the eastern US, hurricanesusually form over the warm waters of the Caribbean Sea and travel north. When they are over the col
garik1379 [7]

Answer:

Less powerful

Explanation:

Hurricanes rely on warm water. It sucks heat energy from the water to use for fuel. Warmer water means more moisture, which also mean a bigger and/or stronger hurricane. The North Atlantic is definitely much colder than the Caribbean so the hurricane will not have much fuel.

Have a great day!

At room temperature, sound travels at a speed of about 344 m/s in air. You see a distant flash of lightning and hear the thunder
beks73 [17]

Answer:

d=1.67mi

Explanation:

Assuming the light takes essentially no time to reach you, the distance at which the lightning occurred can be calculated by multiplying the speed of sound by the time it takes to hear the thunder:

d=v_st\\d=344\frac{m}{s}(7.8s)\\d=2683.2m*\frac{1mi}{1609.34m}=1.67mi
