Is refractive index of air less than vacuum?
No, refractive index(RI) of air is more than that of vaccum. Infact RI of any medium is more than vaccum. RI of vaccum is 1. RI of any medium = c/v where c is speed of light in vaccum v is speed if light in medium whose RI with respect to vaccum is found. It is known that speed of light is maximum in vaccum so v < c, and RI > 1.

Why does your car make a whistle noise when driving but goes away when stepping on brakes or gas?
You have a vaccum leak. When you step on the brake, vaccum is being used to help the power assist, thus lessening the amount in the engine available to leak. The reason it goes away when you accelerate is that vaccum drops low on acceleration too.

What would cause 1989 Ford Contour V6 to surge 300 to 500 RPM while idling?
Generally a surge at low RPMS is caused by a defective vaccum componet or a cracked vaccum line. It still leaks at higher speed but you don't notice it because the engine is GENERATING more volume of vaccum to cover it up. Try this: Take some WD40 and lightly spray it around vaccum lines while the motor is running; as soon as the engine smoothes out you have found the troubled part. The wd40 will TEMPORARILY seal the leak.
