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.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
