Q. Consider the following differences between Webb and Hubble telescope:
  1. While Webb will observe in the infrared range, Hubble in the ultraviolet and visible spectrum.
  2. Hubble is way much smaller than Webb.
  3. Like  Hubble, Webb will orbit the Earth.
Which of the differences given above is/are correct?

Answer: Only 1 & 2
Notes: The James Webb Space Telescope primarily observes in the infrared range, while the Hubble Space Telescope focuses on ultraviolet and visible light. Webb features a larger primary mirror, providing a wider field of view than Hubble. Additionally, Hubble orbits Earth, whereas Webb orbits the Sun at the second Lagrange point (L2), 1.5 million kilometers (1 million miles) from Earth.
