10) Suppose you have a transparent material that is more dense than glass. How would the light ray be
affected? Y

According to the law of reflection, When a ray of light passes from rarer medium to denser medium , it bends towards the normal. So, if there is a transparent material that is more dense than glass then the ray of light will bend towards the normal. The direction of light through the medium is predicted by Snell's Law. According to the Snell's law:

n₁ sin θ₁ = n₂ sin θ₂

Where n₁ is the refractive index of the first medium

n₂ is the refractive index of second medium.

θ₁ and θ₂ are the angle of incidence of light in medium 1 and medium 2

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
