    I can't say for sure about foil, but I've bounced my TV remote signal off of metallic surfaces just as an experiment and it worked. Same for a standard mirror.

    Yes, it does. Particularly near infrared; for far infrared, telescopes use gold-coated optics, however, since gold reflects those wavelengths better than does aluminum.
