Which of the following defines the wavelength of a wave?
2 answers:
Answer:
the distance between peaks of a wave
Explanation:
A wave is characterized by regular crests (peaks) and troughs (valleys). The wavelength of a wave is essentially the distance between two crests or two peaks. It is represented by the greek letter lambda, λ.
For a wave travelling with a speed c and having a frequency ν, the wavelength is given by the ratio of speed to the frequency. Mathematically it can be represented by the following formula:

Answer:
The intermediate is carbocation.
Explanation:
The reaction of alkene with an acid to give alcohol is an electrophilic addition reaction.
In electrophilic reaction, the alkene is being attacked by an alkene.
in case of aqueous acid reaction with alkene , the electrophile is [H⁺].
When the proton attacks the alkene it generates carbocation.
The carbocation generated is formed based on stability of carbocation.
The mechanism is shown in the figure.
