State whether the following is true or false.
Two samples that match visually may reflect quite differently in the infrared.

  • A.True
  • B.False
  • C.True only at large scales
  • D.False only at small scales

Answer: A

Nothing in a visual match constrains the reflectance outside the visible. Applications using infrared detection must specify that band separately. A visual match says nothing about the infrared. That band must be specified separately.
