Question

Which of the following will show
Tyndall effect?​

Answer 1

Tyndall effect is shown by those mixtures which are colloids. This is because colloids have suspension of small particles, from 1 – 1000 nanometres in size which can scatter light falling on them, a phenomenon called as Tyndall effect.
