7nadin3 [17]
Answer: 1.88

Explanation

Applying Snell’s Law, sin(1)/sin(2) = n(2)/n(1), where n is the index of refraction and sin 1 and 2 being of incidence and refracted respectively.

1) sin35/sin24 = n(2)/1.33
2) 1.41 = n(2)/1.33
3) n(2) = 1.41 x 1.33
4) n(2) = 1.88

Hope this helps :)

A pitcher releases a fastball that moves toward home plate.
Vsevolod [243]

The two additional forces that act on the ball as it travels between the pitcher and the home plate are air resistance and gravity.

<h3>What are the forces that affect object in motion;</h3>
  • Air resistance: this is the force that oppose the motion of an object in air due to frictional force
  • Gravity: this is the force due to weight of the object and acts downwards.

The two additional forces that act on the ball as it travels between the pitcher and the home plate include:

  1. Air resistance and
  2. Gravitational force  

<h3>How the forces affect the motion of the ball</h3>
  • Air resistance oppose the motion of the ball as it travels in air.
  • Gravity is the force due to weight of the ball and acts downwards.

This is the path of light through slits.

what are incident light ?

The light that hits a topic is called as incident light. It may originate from an artificial source or from a natural source, like as the sun. Incident light is also light that reflects off a reflector or another surface.

what is light ?

The region of the electromagnetic spectrum that the human eye sees as light, or visible light, is composed of electromagnetic radiation. The Sun is the primary source of natural light on Earth.
