Answer:

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction

<span>Although a star might look brighter than the Sun, a comparison of its absolute<span> magnitude might help prove that they have the same real brightness.
Absolute magnitude is a concept that compares the absolute brightness of celestial objects. The absolute magnitude of an object is defined as the apparent magnitude it would have if it were viewed at a standard distance of 10 parsecs (32.6 light-years) with no dimming of its light. The more luminous an object, the smaller the numerical value of its absolute magnitude.</span></span>

  • A multi-cellular organism is made up of several cells.
  • A cell is a very small microscopic structure.
  • It is usually described as the fundamental unit of life.
  • Due to its small size, the naked eyes cannot see it
  • The invention of the microscope opened up the world of cells.
  • Since they have been around for a long time, distinction of cells would have been made possible at those times using a microscope.
