4268.Which of the following are illustrations of total internal reflection?
1) Shining of air bubble in water
2) Sparkling of diamond
3) Increase in duration of sun’s visibility
4) Mirage and looming
5) Ophthalmoscope
Choose the appropriate code:
1, 2, 3 and 4 only
1 , 2 and 5 only
1, 2, 3 and 5 only
All of the above
Explanation:

Total Internal Reflection:
• If light is propagating from denser medium towards the rarer medium and angle of incidence is more than critical angle, then the light incident on the boundary is reflected back in the denser medium, obeying the laws of reflection. This phenomenon is called total internal reflection as total light energy is reflected, no part is absorbed or transmitted.
• For total internal reflection,
1) Light must be propagating from denser to rarer medium
2) Angle of incidence must exceed the critical angle

4283.Which among the following can effectively be examples of ‘Secondary Succession’?
1. Formation of a new Island after volcanic eruption 2. The renewal of a forest after a fire 3. A flooded land 4. The renewal of a crop after harvesting
Select the correct option
1, 2 and 3
2, 3 and 4
1, 3 and 4
All
Explanation:

Examples of secondary succession include: ? The renewal of a forest after a fire: The fire itself destroys a majority of different types of trees and plant life. Because seeds and roots and other plant and tree parts remain in and on the soil, gradually the plants and trees begin to grow again and eventually return to the state of the original ecosystem.
The renewal of a crop after harvesting: A crop is completed harvested when it becomes ripe. Without new seeds being planted, the crop can regenerate the following year due to the plants and seeds that remained after harvesting. ? A forest renews after logging: A large amount of trees were chopped down by loggers in order to create building materials. Over time, trees grow in and the area returns to its previous state. ? Renewal after disease: A plant population can be very negatively affected by a variety of infectious plant diseases. If the entire population dies, but the soil and roots remain, it is possible for secondary succession to occur and for the population of those plants to return. ? A flood can ruin farmlands. However, because the soil remains after the waters recede, over the course of many years a natural secondary succession can occur and the vegetation that had previously grown there can grow again. ? Plants can be very susceptible to attack from pests, particularly if there is an overpopulation of those pests. When this occurs, the plant population in one area can be completely destroyed. However, when the pest overpopulation is resolved, the plants are able to live again and thrive in the soil in which they previously had lived.

4287.Consider the following assumptions regarding Pugmark method

2. All the four paw prints of every individual tiger in the surveyed area had to be detected during the censuses.
3. The same hind pugmark of each one of these individual tigers must be lifted from suitable and comparable substrates or from standardized soil track-plots.
4. The shape of each pugmark lifted had to be recorded without distortion by the thousands of census personnel involved in the operation.
5. Supervisory officials were expected to be subsequently able to segregate the pugmarks of each individual tiger correctly, based on footprint shape, track measurements, and prior local knowledge.
Select the appropriate code
Failure of assumptions 1 and 2 would lead to under-counts
