Test: GIS, GPS & Remote Sensing- 2 - Question 1

### The relation between velocity, wavelength and frequency can be given as _________

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 1

Photons are the main constituent particles in the electromagnetic energy. The relation between velocity, wavelength and frequency is determined as λ = c / f, where λ represents wavelength, f is the frequency of the wave and c represents the velocity of the wave, which is equal to speed of light.

Test: GIS, GPS & Remote Sensing- 2 - Question 2

### Remote sensing uses which of the following waves in its procedure?

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 2

Electro-magnetic waves are used in case of remote sensing. The different waves present in this spectrum enables us to use a variety of waves based on the condition present and can be able have a better output.

### Which of the following is not a principle of remote sensing?

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 3

Remote sensing involves certain principles which are applied for having a good result of the desired output. The principles are electromagnetic energy, electro-magnetic spectrum, interaction of energy with atmosphere etc.

Test: GIS, GPS & Remote Sensing- 2 - Question 4

Which among the following waves is having less wavelength range?

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 4

A wide range of waves are present in case of electromagnetic spectrum, off which the gamma-rays are having a nano level wave length capacity i.e., less than 0.03nm.

Test: GIS, GPS & Remote Sensing- 2 - Question 5

In visible region, the blue light is having a wave length range of __________

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 5

Visible region consist of three color waves red, blue and green remaining are the combination of those. The blue light is having a wavelength range of 0.42-0.52 micrometer.

Test: GIS, GPS & Remote Sensing- 2 - Question 6

Which of the following field is used by the EM waves?

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 6

EM waves used two major sources of fields i.e., electric and magnetic fields. Both are placed orthogonal to each other in a wave pattern. The electric components are placed in vertical manner and magnetic components in horizontal manner.

Test: GIS, GPS & Remote Sensing- 2 - Question 7

Among the following, which describes Stefan- Boltzmann formula?

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 7

Stefan- Boltzmann law is based on the radiation produced and emitted by the body. This can be mathematically represented by M = σ*T4. Here, α is the Stefan- Boltzmann constant, T is the absolute temperature, M is the spectral existence of the body.

Test: GIS, GPS & Remote Sensing- 2 - Question 8

Which of the following is not a classification of scattering principle?

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 8

Scattering involves in distribution of the light ray in more than two directions. It can be further classified as Rayleigh scattering, Mie scattering, non-selective scattering.

Test: GIS, GPS & Remote Sensing- 2 - Question 9

Which of the following can act as an example for air-borne platform?

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 9

At present, the air-borne platforms in use are Dakota, AVRO and beach-craft. A sensor is mounted on them and is placed at an altitude which can be able to access the specified object.

Test: GIS, GPS & Remote Sensing- 2 - Question 10

Polar orbiting satellites are generally placed at an altitude range of __________

Detailed Solution for Test: GIS, GPS & Remote Sensing- 2 - Question 10

Polar orbiting satellites are also known as sun-synchronous satellites, which are generally placed at an altitude range of 700-1500km from the ground level. These are able to deliver accurate information about the object which we need access to.
