Multiple choice physics observing space: telescopes space research and satellites space travel space exploration and forms of light

The final image formed by an astronomical telescope is:

  1. real and erect.

  2. virtual and erect.

  3. real and inverted.

  4. virtual and inverted.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The objective lens produces a real, inverted image and the eyepiece acts as a simple magnifier and does not re-invert and produces a virtual image. So overall the image is inverted and virtual.

Salyut 6 and Salyut 7, were built with:

  1. three docking ports

  2. two docking ports

  3. five docking ports

  4. No docking ports

B Correct answer
Explanation

Salyut 6 and Salyut 7 were the second generation of the Salyut programme which was the first space station programme undertaken by the Soviet Union. They both were built with two docking ports, one on either end of the station.

The space stations so far launched are broadly classified into two types:

  1. Mir and Skylab

  2. Apollo and Salyut

  3. Monolithic and Modular

  4. Almaz and Salyut
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The space station launched are broadly classified into two types: 

  1. Monolithic : earlier space station, Salyut and Skylab in which were constructed and launched in one piece, and then manned by a crew later. 
  2. Modular: Mir and ISS, a core unit was launched, and additional modules, generally with a specific role, were later added to that.

Which of the following is cannot be considered as the use of space stations?

  1. Space station is used to study the effects of long-duration spaceflight on the human body

  2. Space station provides a platform for greater number and length of scientific studies than it is available on other space vehicles.

  3. Space stations are used both for military and civilian purposes.

  4. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Space stations are made to conduct experiments that needs to be done out in space. It is used to study the effects of long-duration space flight on human body. These provides a platform for greater number and length of scientific studies than it is available on other space vehicles and other military and civilian purposes.

The number of wavelengths in the visible spectrum is :

  1. $4000$
  2. $6000$
  3. $2000$
  4. $inifinite$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. 
  • It ranges in wavelength from approximately 400 nanometers ($4 \times  10 ^{-7}$ m, which is violet) to 700 nm ($7 \times 10^{-7}$ m, which is red).
  • Hence wavelengths are infinite
  • Option D is the right answer

Choose the correct answer from the alternatives given.
Which of the following ray are not electromagnetic waves

  1. X-rays
  2. $\gamma- $ rays
  3. $\beta -$ rays

  4. Heat rays
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cosmic rays, γ-rays, and X-rays are part of electromagnetic spectrum, while β-rays are emitted by radioactive elements. Hence β-rays is not electromagnetic waves.
