What is the need to use telescope in spectrometer?
The collimator present in a spectrometer convert the rays from the source to parallel rays .Telescope is used to watch the parallel rays which means for the telescope the object is located at infinity.so that we use telescope.
What is the purpose of the collimator?
allow only parallel rays from strem of rays
How does an equatorial mount in a telescope work?
An equatorial mount in a telescope is designed to align with the Earth's axis of rotation, allowing the telescope to track celestial objects as they move across the sky. By using an adjustable axis parallel to the Earth's axis, the telescope can compensate for the Earth's rotation, providing smooth and accurate tracking of stars and other celestial objects. This makes it easier for astronomers to observe and photograph objects in the night sky for extended periods of time without having to constantly adjust the telescope's position.
What is the difference between a terrestrial telescope and a astronomical telescope?
A terrestrial telescope is designed for viewing objects on Earth, such as landscapes and wildlife, while an astronomical telescope is designed for viewing celestial objects like stars, planets, and galaxies in the night sky. Astronomical telescopes typically have larger apertures and higher magnification capabilities to observe objects that are much farther away than those seen with a terrestrial telescope.

How do you get parallel beams of light?
Parallel beams of light can be created by using a collimator, such as a lens or a mirror, to straighten and align the light rays in a parallel manner. This involves focusing the light from a source into a beam and then passing it through a collimating device. The collimator helps to eliminate any divergence of the light rays, resulting in parallel beams.
What is use of collimator in spectometer?
A collimator in a spectrometer is used to ensure that light enters the spectrometer in a parallel beam, which helps in improving the accuracy and precision of the spectral measurements. It helps to reduce divergent light and focus the light onto the entrance slit of the spectrometer, resulting in more accurate spectral data.
True or false when you come closer to a distant object with a telescope the rays become less parallel?
True. When you come closer to a distant object with a telescope, the rays of light entering the telescope become less parallel as the object appears closer, and the lens or mirror in the telescope needs to adjust the focal length to focus properly on the object.
Why does light from stars arrive at a telescope as parallel rays?
Light from stars arrives at a telescope as parallel rays because stars are very far away compared to the size of a telescope's aperture. This distance makes the light rays effectively parallel when they reach the telescope, similar to how sunlight reaches Earth as parallel rays.
Why you are using parabolic shape for radio telescope?
A parabolic shape is used for all reflecting collectors ... visible light telescope, radio telescope, satellite receiver, etc. A parabolic reflector directs all parallel incoming rays toward one point, called the 'focus' of the parabola.
What is a motor drive telescope?
It is a telescope on an equatorial drive (one axis parallel to the Earth's axis). An electric motor drives the other axis at 15 degrees per hour to follow an object as it moves across the sky.
How does an equatorial mount in a telescope work?
An equatorial mount in a telescope is designed to align with the Earth's axis of rotation, allowing the telescope to track celestial objects as they move across the sky. By using an adjustable axis parallel to the Earth's axis, the telescope can compensate for the Earth's rotation, providing smooth and accurate tracking of stars and other celestial objects. This makes it easier for astronomers to observe and photograph objects in the night sky for extended periods of time without having to constantly adjust the telescope's position.
What is construction of spectrometer?
A spectrometer typically consists of a light source, a collimator to create a parallel beam of light, a diffraction grating or prism to disperse the light into its spectral components, and a detector to capture and measure the intensity of the different wavelengths of light. The spectrometer then produces a spectrum displaying the intensity of light at different wavelengths.
Why does dispersion take place in only a prism and not in a glass slab?
The light strikes on one surface of the prism undergoes refraction and passes through the glass of the prism, and when emerges out, it refracts again. This causes the dispersion of the light and splits the light into its constituent colours. The degree of bending depends on the angle at which the ray of light enters and leaves the faces of the prism. The faces of the prism are not parallel to each other. For a glass slab, the opposite faces of the slab are parallel. So only a slight deviation occurs.
Why there is no dispersion of light refracted through a rectangular glass slab?
Dispersion of light occurs due to different colors of light having different speeds in a medium. When light passes through a rectangular glass slab, the different colors of light follow the same path, experiencing the same amount of refraction. This results in no dispersion of light as all colors exit the slab without separating.
