Answer / Anjali Verma
$rootScope can be used to broadcast and listen to events across different scopes. Here's an example:
```javascript
// Broadcasting event from a child scope
$scope.$broadcast('eventName', data);
// Listening to the event in a parent scope
$rootScope.$on('eventName', function(event, data) {
console.log(data);
});
