rewona [7]3 years ago
4 0
A wave can be described as the disturbance of particles in an area. Think about it this way: particles (matter) carry energy. For all the laws of physics to work, this energy must be "traded" somehow. This happens by miniscule vibrations in the particles, which are apparent disturbances. This creates a wave, and therefore a wave is, indeed, a disturbance.<span />

A red laser beam goes from crown glass with refraction index n=1.3 to air (n=1) with an incident angle of 0.23 radians. What is
Klio2033 [76]

Answer:

   θ = 10.28º

Explanation:

To find the angle of refraction use the equation of refraction

        n₁ sin θ₁ = n₂ sin θ₂

where index 1 is for incident light and index 2 is for refracted light.

         sin θ₂ = n₁ / n₂ sin θ

let's calculate

         sin = 1 / 1.3 sin 0.23

         sin = 0.175

        θ= 0.17528 rad

let's reduce to degrees

       θ = 0.17528 rad (180ª / pi rad)

       θ = 10.28º

Which observational tool helped astronomers Arno Penzias and Robert Wilson discover the
iren2701 [21]

Answer:

A radio telescope helped the astronomers discover the CMB.

Explanation:

  • Penzias and Wilson while experimenting with a radio telescope in 1964, accidentally discovered the radiation that exists universally also known as the CMB.
  • This was used to support the "Big Bang Theory" and not the "Steady State Theory"
  • CMB is the faint cosmic radiation that fills up the universe. It provides important data for understanding early universe.
  • This data tells us about the composition of the universe and its age which raises new questions about the universe.
