"啪 (pā)" is similar to "pop!" in English. However, you could use it in so many situations and depending on the situation, the meaning doesn't directly translate into "pop".
For example, when joking with your friends and pretending that you'd smack them for an inappropriate joke, you can make the motion of hitting (but purposely missing) them while saying “啪!" If you do a couple of slaps, say three back and forth then say "啪,啪,啪!"
Though the first example is the most common way to use this word, another way to use "啪" can be describing something that’s fallen. "我的手机啪就掉下马桶了" or "My cell phone fell into the toilet, plat!"
When walking on the street and all of a sudden you see an interesting sign that is hanging in the window of a shop you can say "我走在马路上的时候，啪，就看到了标记" meaning "When I was walking on the street, voila, I saw the sign."

A great way to express surprise or "whoa!" would be 哇塞 (wa sāi). You can use this is together with "厉害" (powerful; strong). If one of your coworkers went to work only wearing a t-shirt when it was 50 degrees out to teach his class. All the students would tell him "哇塞, 好厉害!" or "Whoa! So strong!"
