What is the actual use of six thermometer?
It consists of a U-shaped glass tube with two separate temperature scales set along each arm of the U. One of these is for recording themaximum temperature encountered and the other for the minimum temperature. The arms of the U-shaped tube terminate in sealed glass bulbs. The bulb at the top of the minimum reading scale arm is full of alcohol, the other contains a vacuum (or low pressure alcohol vapour). [1] [2] In the bend of the U is a section of mercury. This is pushed around the tube by the thermal expansion and contraction of the alcohol in the first bulb as it responds to the external temperature. The near vacuum in the other bulb allows free movement of the alcohol and mercury. It is the alcohol which measures the temperature; the mercury indicates the temperature reading on both scales. The thermometer shows a reading at the top of the mercury section on both the maximum and minimum scales; this shows the current temperature The maximum and minimum readings are recorded by two small steel markers which are sprung into the capillary tube so that they cannot easily slide unless a small force is applied to them. Before a maximum or minimum reading can be taken, both markers must be returned to the top of the mercury, usually by hand using a small magnet to slide them along the tube. Any change in temperature after that time will push one of the markers along with it. If the temperature is rising, then the maximum scale marker will be pushed. If it falls after the reset, then the moving mercury will push the minimum scale marker. Often both things happen one after another as the temperature changes, say through a twenty-four-hour period (see diurnal temperature variation). The markers thus record the furthest point reached by the mercury in each arm of the tube. They record the extremes of temperature experienced by the device since it was last reset. The thermometer is usually reset every day, but if left for longer the readings would show the highest and lowest temperatures encountered since the instrument was last reset. To take a reading, the positions of the ends of the markers nearest to the mercury are examined. Their positions on the maximum and minimum scales show the highest and lowest temperatures encountered over the period of measurement
What is the minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees?
The minimum index of refraction for total internal reflection at a 45-degree angle is 1.41. This means that the glass or plastic prism would need to have an index of refraction greater than or equal to 1.41 to achieve total internal reflection at that angle.
What is the minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45.0 and 8728?
To achieve total internal reflection in a prism, the index of refraction (n) must be greater than the sine of the critical angle. For a critical angle of 45 degrees, the minimum index of refraction can be calculated using ( n = \frac{1}{\sin(45^\circ)} ), which gives ( n = \sqrt{2} ) or approximately 1.414. Therefore, the minimum index of refraction for a glass or plastic prism used in binoculars must be at least 1.414.
A thin layer of oil with index of refraction 1.28 is floating on water what is the minimum thickness of the oil in the region that reflects green light of wavelength 536 nm?
The minimum thickness of the oil film should be equal to half the wavelength of light in the oil medium (because of phase change upon reflection). The formula for minimum thickness is: t = λ / (2 * n), where t is the thickness, λ is the wavelength of light, and n is the refractive index of the medium. Plugging in the values, we get t = 536 nm / (2 * 1.28) ≈ 209.4 nm. So, the minimum thickness of the oil film should be approximately 209.4 nm.
What function can be used to find the answer located in a vertical table?
A lookup function like VLOOKUP or INDEX/MATCH can be used to find the answer located in a vertical table. VLOOKUP searches for a value in the first column of a table and returns a value in the same row from a specified column, while INDEX/MATCH combination can retrieve a value at the intersection of a certain row and column based on matching criteria.
How does a minimum thermometer works?
A minimum thermometer works by using a small column of mercury or alcohol that moves up as temperature increases and down as temperature decreases. A small steel index marker within the column remains at the lowest temperature reached, allowing users to see and record the minimum temperature.
What is the index of a thermometer?
The index of a thermometer is the scale or numerical reference used to indicate temperature readings. It can be in either Celsius or Fahrenheit, depending on the type of thermometer.

What are the uses of 6s maximum and minimum thermometer?
Six's maximum and minimum thermometer is a popularthermometer among gardeners for use in greenhouses. Its purpose is to record the maximum and minimum temperatures reached since the thermometerwas last read. Generally speaking a minimumtemperature occurs during the night and amaximumduring the day. It was invented by James Six towards the end of the eighteenth century, and consists of a fairly large cylindrical bulb full of alcohol, or oil of creosote, connected by a U- shaped stem to a second bulb nearly full of alcohol or oil of creosote. The bend of the U contains athread of mercury. Two scales are provided, one against each limb of the tube so that thetemperature may be read against either of themercury levels. Resting on each of the mercurysurfaces are small steel indexes provided with light springs to hold them in position in the stem.Expansion or contraction of the fluid in the larger bulb causes a movement of themercury thread. Consequently, one or other index is pushed forward by the mercuryand left in the extreme position reached. Thus, the lower end of the index on the left indicates the minimum and that on the right themaximum temperatureattained. It is interesting to note that Six's maximum and minimum thermometers were still being used in 2000 of exactly the same design and construction as ones produced over 100 years ago.
What is the minimum value of the refractive index?
The minimum value of the refractive index is 1, which corresponds to a vacuum. The refractive index of a medium is always greater than or equal to 1.

What is the minimum Body Mass Index for a clinically severe obese person?
baseline minimum is 30.
What is the maximum age on an index fossil?
20 MYR.
What does a max min thermometer do?
Mercury expands on heating.so at noon when the sun is overhead in the thermometer the Mercury expands and pushes the index down.And then the alcohol which is half filled in the maximum tube rises.then the max.temp is taken.
What is the minimum CBR for subgrade?

What is the minimum deviation of prism whose refractive index is three to the power half?
The minimum deviation of a prism can be calculated using the formula: δ = (n - 1)A, where δ is the minimum deviation, n is the refractive index of the prism, and A is the angle of the prism. If the refractive index of the prism is three to the power of half, or √3, and the value of A is known, the minimum deviation can be calculated using the formula.
