The highest parts of a transverse wave are called a. troughs. b. crests. c. nodes. d. wavelengths.

In Section 5.6, we learned that triple bonds are stronger and shorter than single bonds. For example, a C-CC-C single bond has an average bond energy of 347 kJ/molekJ/mole, while a C≡CC≡C triple bond has an average bond energy of 837 kJ/molekJ/mole.
