Which of the following is not true about the total lunar eclipse?

Options

  1. AA lunar eclipse can occur on a new moon and full moon day
  2. BThe lunar eclipse would occur roughly every month, if the orbits of earth and moon were perfectly coplanar
  3. CThe moon appears red during the eclipse because the blue light is absorbed in earth's atmosphere and red i
  4. DA lunar eclipse can occur only on a full moon day

Correct answer

A. A lunar eclipse can occur on a new moon and full moon day

Step-by-step solution

A lunar eclipse occurs only on a full moon day. So, option (a) is incorrect.
