Each index contour has an elevation associated with it. When you look at 2 contours, one will have a higher corresponding elevation. As you go from the lower elevation to the higher elevation, you know that the land is increasing in the direction toward the higher elevation. From the higher to the lower elevation, the land is decreasing (sloping downward, decreasing in elevation).

Differences between relative refractive index and absoulate refractive index?

Refractive Index(i) Refractive index of a medium is that characteristic which decides speed of light in it.(ii) It is a scalar, unit less and dimensionless quantity.(iii) Absolute refractive index :When light travels from vacuum to any transparent medium then refractive index of medium w.r.t. vacuum is called it's absolute refractive index i.e. vacuumµmedium = c/vAbsolute refractive indices for glass, water and diamond are respectively µg = 3/2 = 1.5, µw = 4/3 = 1.33 and µD = 12/5 = 2.4(iv) Relative refractive index :When light travels from medium (1) to medium (2) then refractive index of medium (2) w.r.t. medium (1) is called it's relative refractive index i.e. 1µ2 = µ2/µ1 = v1/v2 (where v1 and v2 are the speed of light in medium 1 and 2 respectively).(v) When we say refractive index we mean absolute refractive index.(vi) The minimum value of absolute refractive index is 1. For air it is very near to 1. ( 1.003)

How do index contours let you know if the land you are viewing is increasingor decreasing in elevation?

Index contours are thicker and usually labeled with their elevation. By identifying the index contours on a topographic map, you can determine if the land is increasing or decreasing in elevation. If the index contours are closer together, the land is steep, indicating a rapid change in elevation. Conversely, if the index contours are further apart, the land is gradually increasing or decreasing in elevation.


How do index contours let you know if the land you are viewing is increasing or decreasing in elevation?

Index contours are typically marked by bold lines and indicate specific elevation levels on a topographic map. By observing the spacing between these index contours, you can determine if the land is increasing or decreasing in elevation; closely spaced contours indicate steep terrain, while widely spaced contours suggest a gentle slope. If the index contours are ascending in elevation as you move in a particular direction, the land is increasing in height; conversely, if they descend, the land is decreasing in elevation.


How can index contours be identified?

Index contours on a topographic map can be identified by looking for thicker contour lines compared to the surrounding lines. They are typically labeled with their elevation value. Index contours are used to provide a quick reference to the elevation changes on the map.


How is an index contour usally indicated?

An index contour is typically indicated on a topographic map by a bold line, often labeled with its elevation in feet or meters. These lines are usually spaced at regular intervals, such as every 100 or 500 feet, and help to provide a clear reference for understanding the terrain's elevation changes. In addition to the index contours, intermediate contours may be shown as lighter, thinner lines between the index contours.


What is difference in elevation between two successive index contours on a map with a contour interval of 5 m?

The difference in elevation between two successive index contours on a map with a contour interval of 5 meters is exactly 5 meters. Index contours are typically marked with heavier lines and are used to indicate elevation at specific intervals, in this case, every 5 meters. Therefore, each standard contour line between the index contours represents a change in elevation of 5 meters as well.


What is intermediate contours?

Intermediate contours refer to the contour lines on a topographic map that represent elevations between the index contours, which are typically marked with a heavier line and labeled with their elevation. These intermediate lines help to illustrate the terrain's shape and steepness, providing essential details about the landscape. They are usually spaced evenly between index contours, allowing for a more precise understanding of elevation changes in a given area.


What is the function of index contours?

Index contours are used on topographic maps to represent elevation changes and to help users easily interpret the terrain. They are typically bolded or labeled lines that indicate significant elevation levels, usually spaced at regular intervals, such as every 100 or 500 feet. By providing a clear reference point, index contours facilitate navigation and understanding of the landscape’s relief. Additionally, they aid in estimating the steepness of slopes and the overall topography of the area.


How far apart would two successive index contours be on a map with a contour interval of 5 meters?

Two successive index contours would be 10 meters apart on a map with a contour interval of 5 meters. This means that each index contour line represents a change in elevation of 10 meters from the next adjacent line.


Specially drawn contour lines used to represent a round number of feet or meters?

Index contours are specially drawn contour lines that represent a specific round number of elevation, usually labeled with the exact value. They are useful for quickly identifying key elevation points on a topographic map.


What are the current bloomberg futures?

How do you think increasing a medium's index of refraction might affect the angle of refraction?

Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.


Why are some contours thicker than others?

Contour lines represent elevation on a topographic map. Thicker contour lines are known as index contours and typically represent a significant change in elevation, such as a peak or ridge. They help the reader quickly identify major landforms on the map.
