The energy gap of silicon is `1.14 eV`. The maximum wavelength at which silicon will begin absorbing energy is

A

`10888Å`

B

`1088.8Å`

C

`108.88Å`

D

`10.888Å`

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda_(max)=(hc)/E=(6.6xx10^(-34)xx3xx10^(8))/(1.14xx1.6xx10^(-19))=10888Å`
