Question

The range of wavelengths for visible light is between _______.

Options
  • A

    4.6 x 107 to 7.8 x 10 -7 m

  • B

    4.0 x 10 -7 to 7.6 x 10 -7 m

  • C

    4.0 x 10 -6 to 7.6 x 10 -6 m

  • D

    4.0 x 10 -8 to 7.6 x 10 -8 m

Explanation

The range of visible light is from 400nm to 760nm. Conversion of 400nm to meters will be 400x10-9=4x10-7. Conversion of 760 nm to meters will be 760x10-9=7.6x10-7.

Hence the answer is B.

The range of visible light is from 400nm to 760nm. Conversion of 400nm to meters will be 400x10-9=4x10-7. Conversion of 760 nm to meters will be 760x10-9=7.6x10-7.

The range of visible light is from 400nm to 760nm. Conversion of 400nm to meters will be 400x10-9=4x10-7. Conversion of 760 nm to meters will be 760x10-9=7.6x10-7.
