Media a, b, c, and d represent different mediums. the phenomenon in this diagram is best described as
a) diffraction
b) dispersion
c) reflection
d) refraction

D)refraction

Step-by-step explanation:

causes an object to appear bent as waves pass from one medium to another. The arrows in this diagram appear bent and are passing from one medium to another, so the diagram is showing refraction.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

may i see the picture? it would a lot, xox
