The number of photo electrons emitted for light of a frequency $\upsilon$ (higher than the threshold frequency $v_0) $ is proportional to
- threshold frequency $(v_0) $
- intensity of light
- frequency of light (v)
- $v-v_0 $
The Correct Option is B

Alcohols, Phenols and Ethers - Classification
Classification of Alcohols Phenols and Ethers are as follows:
On the basis of dependence on the attachment of hydroxyl groups, alcohol can be classified into three different types:
- Monohydric alcohols
- Dihydric alcohols
- Trihydric alcohols
On the basis of dependence on the different number of carbon atoms in a molecule that are bonded with the -OH group, alcohol can be classified into three different types:
- Primary alcohols
- Secondary alcohols
- Tertiary alcohols
On the basis of the attachment of the different number of hydroxyl groups, the phenols can be classified further into three types:
- Monohydric phenols
- Dihydric phenols
- Trihydric phenols
The Classification is dependant on the type of the alkyl or aryl groups attached to the oxygen atom in ether group, thus it can be classified into two types:
- Symmetrical ether
- Unsymmetrical ether
