Unless the light ray strikes the medium at an angle of 90°

The phenomenon of bending of light when going from one medium to another is referred to as refraction. However, refraction is only possible when the light ray is not perpendicular to the medium. If the light is perpendicular, it passes through without refracting.

Which of the following is a correct step in the process of adding 8.0 x 10^ -2 and 6.0 x 10^ -3

dybincka [34]

Explanation:

In order to compute correctly the sum of the two terms, we have to rewrite one of them such that they have the same exponent.

The two terms are:

$8.0 \cdot 10^{-2}$

$6.0 \cdot 10^{-3}$

For instance, we can re-write the second term such as it also has a power $10^{-2}$ . In order to do that, we have to move the decimal point one place to the left, therefore:
