There is a reflection at the boundary between two materials if there is a change of<u> the speed of light in the material </u>at the boundary.
This bending is referred to as refraction. whilst a wave traveling at an angle adjusts its velocity upon crossing a boundary among materials,. This bending is known as refraction. As a wave crosses a boundary into a new medium, its pace, and wavelength exchange simultaneously as its frequency stays equal.
While light from air hits a smooth piece of glass (n = 1. five) with the ray perpendicular to the glass floor, of the subsequent will occur while light from air hits a clean piece of glass with the ray perpendicular to the glass surface, the part of the light passing into the glass: will now not exchange its frequency.

Answer:
x = 2
Step-by-step explanation:
From the question we are given the algebraic sign with the Inequality sign
95 - 2x < 7 (15x - 17)
In order to find all the possible values of x that makes the algebraic expression true ,
We solve for this by convert the less than(<) sign to =
A true statement or algebraic expression is when both values on the left hand side and right hand side of and algebraic expression is the same of equal to each other.
Therefore:
95 - 2x = 7 (15x - 17)
95 - 2x = 105x - 119
Collect like terms
95 + 119 = 105x + 2x
214 = 107x
x = 214/107
x = 2
In other to confirm if x = 2 makes the expression true
95 - 2x = 7 (15x - 17)
95 - 2x = 105x - 119
95 - 2 × 2 = 105 × 2 - 119
95 - 4 = 210 - 119
91 = 91
Therefore, the possible values for x that make the statement true is x = 2
