The change in direction of the sun’s light as shown here is an example of

b

question 7 options:

a. absorption.

b. diffraction.

c. reflection

d. refraction

The answer is refraction.  

Absorption is when no light is reflected back, diffraction is where light bends around a corner, reflection is like taking and shining a flashlight against a mirror, and refraction is like when you put a straw in water and it looks like the straw is not straight.  Same principle with light, it bends in water.  

Hope I helped.  

By dividing you can find the answer

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.
