Refractive index of transparent medium is defined as the ratio of speed of light in vacuum to the speed of light through medium.

That is, Refractive index, n=c/v. Where, Speed of light = c Speed of light in medium = v

It has no unit because it is a ratio of two quantities of same type (speed).

Glass has higher refractive index (1.52) than water, because refractive index of water is 1.33.

The Sun can be seen 2 minutes before the actual sunrise and two minutes after the actual sunset

it means we can say that advance of the sunrise and delay of the sunset in by two minutes

so before understanding this advance and delay, let us understand how a person is able to see the sun

if we assume the earth is a sphere or in the front view, we we have a circle

and a person is standing on the circle means on the surface of the earth

and from the observer's eye, there is a horizon, if the sun is above the horizon

it means we can say that advance of the sunrise and delay of the sunset in by two minutes

so before understanding this advance and delay, let us understand how a person is able to see the sun

if we assume the earth is a sphere or in the front view, we we have a circle

and a person is standing on the circle means on the surface of the earth

and from the observer's eye, there is a horizon, if the sun is above the horizon

if the sun is above the horizon, then we can say that a person is able to see the sun and if the sun is below the horizon, then we can say that the person is not able to see the sun

if the sun is above the horizon, then we can say that a person is able to see the sun and if the sun is below the horizon, then we can say that the person is not able to see the sun

Npw, consider the first case when the sun is just rising. it means now sun is below the horizon.

Npw, consider the first case when the sun is just rising. it means now sun is below the horizon.

if sun is below the Horizon, now the person is not able to see the sun from theoretical point of view, let us understand the actual scenario

if the sun is above the horizon, then we can say that a person is able to see the sun and if the sun is below the horizon, then we can say that the person is not able to see the sun

Npw, consider the first case when the sun is just rising. it means now sun is below the horizon.

if sun is below the Horizon, now the person is not able to see the sun from theoretical point of view, let us understand the actual scenario

when light is coming from sun to the observer's eye, light moves from vacuum to atmosphere

when the light is moving from vacuum to atmosphere vacuum is a optically rarer medium and atmosphere is optically denser medium

if the sun is above the horizon, then we can say that a person is able to see the sun and if the sun is below the horizon, then we can say that the person is not able to see the sun

Npw, consider the first case when the sun is just rising. it means now sun is below the horizon.

if sun is below the Horizon, now the person is not able to see the sun from theoretical point of view, let us understand the actual scenario

when light is coming from sun to the observer's eye, light moves from vacuum to atmosphere

when the light is moving from vacuum to atmosphere vacuum is a optically rarer medium and atmosphere is optically denser medium so light bends towards the normal

but the eye of a persons sees straight, when we extend this line a person is able to see the sun which is above the horizon so sun is actually not rising up but the person able to see the sun 2 minutes before the actual sunrise

Npw, consider the first case when the sun is just rising. it means now sun is below the horizon.

if sun is below the Horizon, now the person is not able to see the sun from theoretical point of view, let us understand the actual scenario

but the eye of a persons sees straight, when we extend this line a person is able to see the sun which is above the horizon so sun is actually not rising up but the person able to see the sun 2 minutes before the actual sunrise

similar to the sunrise case, we have a another case that is sunset, in sunset the sun is below the horizon. light from the sun is moving from vacuum to atmosphere

if sun is below the Horizon, now the person is not able to see the sun from theoretical point of view, let us understand the actual scenario

when light is coming from sun to the observer's eye, light moves from vacuum to atmosphere

similar to the sunrise case, we have a another case that is sunset, in sunset the sun is below the horizon. light from the sun is moving from vacuum to atmosphere

So light is bending towards the normal, but our our eyes are straight when we extend this line, we find the sun above the horizon

So light is bending towards the normal, but our our eyes are straight when we extend this line, we find the sun above the horizon

the sun is actually below the horizon but a person is able to see the sun because we can say that the refracted sun is above the Horizon, so we can say that there is 2 minute delay in the sunset

Acids

Acids taste sour – in fact, the German word for acid is sauer.

Because acids can damage cells, our stomach needs a special lining to protect it from the hydrochloric acid used to digest our food.

We are familiar with some acids – citrus fruits, tomatoes and vinegar are acidic

Acids react with most metals including magnesium to create hydrogen gas and a salt – there are lots of different types of salts in chemistry

They also react with a group of substances called carbonates to produce carbon dioxide

gas, salt and water.
