How many iambs per line does a Shakespearean sonnet contain?

Question:

Iambs:

An iamb is a type of metrical foot in a line of poetry chosen for use by the author in order to create a certain rhythm or flow. It is made up of two syllables, an unstressed syllable then a stressed syllable.

Other Types of Metrical Feet:

• Trochee: the reverse iamb. It is made of two syllables, but the stressed syllable comes before the unstressed. "Tiger" is a trochee.
• Anapest: the extended iamb, it consists of two unstressed syllables followed by a stressed syllable. The first line of Edgar Allen Poe's "Annabel Lee" begins with three anapests: "It was many and many a year..."
• Dactyl: the reversed anapest or extended trochee, it has one stressed syllable and then two unstressed syllables. For example, the word "poetry" is a dactyl.
