re: What Is The Difference Between When And While? page 5

When + for a moment verb(emphasis on point)
While + duration action or verb(emphasis on long term)

So,
1 and 2 correct

3. When I was taking a shower, the phone rang(it is wrong)

4. While the phone rang, I was taking a shower.(it is wrong)
If you think "the ringing lasted throughout the shower", we have to write to
While the phone was ringing, I was taking a shower (my meaning is there are two actions at the same time)

I still do not understand about what your wrote. Please further explain since I would like to know more about this question.

My English speaking friend and I decided the difference is in the length of time.

When is about a single point in time (a moment) like a clap, or a phone ringing, or a drink.

While is about a period of time (duration) like taking a long bath, or going for a long run.

So sometimes they are interchangeable but the emphases changes.

So in some cases it is interchangeable but in some cases it is not.

A lot of thanks that was too useful
