When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
Immersion heaters are used for heating water in a hot water tank. Immersion heaters are usually controlled by thermostat and they will heat your water to a set temperature for as long as you leave it on that setting, or you can have a timer set. It is usually an expensive way to heat water compared to central heating systems with hot water circuits.
During Stage 4 of cold water immersion, the body's core temperature continues to drop, leading to decreased muscle function and coordination. This can result in difficulty breathing, confusion, and eventually unconsciousness if not treated promptly. Medical intervention and rewarming are essential during this stage to prevent further complications and potential death.
After drinking a glass of water, it typically takes about 30 minutes to 2 hours for the water to reach your bladder.
It typically takes about 30 minutes for someone to urinate after drinking a glass of water.
Light will be refracted more when it goes from air to glass, as the refractive index of glass is higher than that of water. Snell's Law states that the angle of refraction is dependent on the refractive indices of the two mediums, with a higher refractive index resulting in a greater change in direction.
When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125
Each substance has an index of refraction. The index of refraction of water is about 1.3330 . The index of refraction of air at standard conditions is about 1.0003 . There is no such thing as the index of refraction of "water to air".
The refractive index of glass is around 1.5, while the refractive index of water is around 1.33. This means that light travels faster in water than in glass. The difference in refractive index is why we observe light bending when it passes from air into glass or water, a phenomenon known as refraction.
The refractive index of water with respect to glass is approximately 1.33. This means that light travels about 1.33 times faster in glass compared to water.
The property being demonstrated is refraction, where light changes speed and direction as it travels from air to water due to the difference in the medium's refractive indices. This causes the pencil to appear bent or broken when viewed through the glass of water.
The power of a lens depends on the differences in the refractive indices of the environment and the lens material. A glass lens immersed in water will loose power (a positive lens will focus at a greater distance). (This is for normal glass with refractive index greater than water - there could be glasses with refractive index less than water in which case the lens would gain power)
The refractive index of water with respect to glass is more than 1. This means that light travels faster in water than in glass, causing the light to bend when it passes from glass to water.
When a light ray travels from glass into water, it changes speed and bends towards the normal (perpendicular line) at the glass-water interface due to the difference in optical density between the two mediums. This phenomenon is known as refraction. The extent of bending is determined by the refractive indices of the materials involved.
Generally, denser mediums have higher refractive index. For example, water has a higher refractive index compared to air. Similarly, glass has a higher refractive index than water.
