In a surveying telescope, the cross hairs are carried by the:
सही उत्तर: ग) Diaphragm
The diaphragm (reticule), held inside the telescope tube, carries the cross hairs and stadia hairs.

Ordinary levelling staves are commonly graduated so that the smallest division is:
सही उत्तर: ख) 5 mm
Common folding and telescopic staves show 5 mm divisions, and readings are estimated to the nearest millimetre.

The angle between grid north and true north at a point on a map projection is called:
सही उत्तर: क) Grid convergence (convergence of meridians)
Grid north follows the projection's grid lines, while true north follows the meridian; the angle between them is the grid convergence.

Neap tides, which have the smallest range between high and low water, occur:
सही उत्तर: घ) Near the first and last quarters of the moon
At the quarter moons the sun and moon pull at right angles, partly cancelling and giving the least tidal range.

An echo sounder records a time of 0.04 s between sending a sound pulse and receiving its echo. Taking the speed of sound in water as 1500 m/s, the depth is:
सही उत्तर: ग) 30 m
Depth = v × t / 2 = 1500 × 0.04 / 2 = 30 m, because the pulse travels down and back.

Three measurements of a length are 10 m, 12 m and 14 m. Using (n − 1) in the denominator, the standard deviation of a single measurement is:
सही उत्तर: ख) 2 m
Mean = 12; Σv² = 4 + 0 + 4 = 8; σ = √(8/2) = 2 m.

In the equatorial system of celestial coordinates, 'right ascension' is measured:
सही उत्तर: क) Eastward along the celestial equator from the first point of Aries
Right ascension, together with declination, fixes a star's position; it is reckoned eastward from the vernal equinox.

The visible part of the electromagnetic spectrum lies approximately between:
सही उत्तर: घ) 0.4 and 0.7 µm
Visible light spans roughly 0.4 µm (blue) to 0.7 µm (red).

'Atmospheric windows' in remote sensing are:
सही उत्तर: ग) Wavelength regions in which the atmosphere transmits electromagnetic energy with little absorption
Sensors are designed to operate in windows such as the visible, parts of the infrared and microwave regions.

-
A 'panchromatic' satellite image is:
सही उत्तर: ख) A single-band image recorded over a broad range of visible wavelengths, shown in black and white
Panchromatic sensors record one broad band, usually giving finer spatial resolution than the multispectral bands.
