Take a lie detector test .
Depends on what it's for...
Yes.
A court can order you to take one, yes.
take a lie detector test
Lie detector tests are not 100% accurate and although given by law they are not admissibly in a court of law and using a lie detector is not used for public use; therefore it would not make any point for your wife to take a lie detector test. Hypothetically, if your wife did cheat she would probably decline taking the test.

If you are not guilty or you know how to beat a lie detector then yes.ADDED: (in the US) The results of such a test are NOT admissibile in court - however - the police CAN use them to assist in conducting their investigations.
A lie detector test follows you pulse, if you are asked a question and your heart rate rises or falls then it will be a lie. If you can regulate your pulse you cannot be detected on a lie detector
