Why is an idle task required in RTOS

1. System stability

Refraining from keeping the system without any task running

2. Power management 

Idle task can be used to implement low power or sleep functions

3. Resource management 

Idle task can be used to implement memory freeing functions and other maintenance activities 

How is a rainbow formed?
