Take the following two sentences:

1. She gave him an apple.


2. She gave an apple to him.

What is the difference between the two sentences?

I heard that the object at the end of the sentence gets more emphasis, but I know that there is no emphasis on the object at the end of the sentence. Instead, the object at the end of the sentence will be new information and the other is old information.

Am I right?
