a.

Give one common use of gamma rays.

[1]
b.

A particular gamma ray has a wavelength of 0.0040.0040.004 nanometres. Which of the following values is equal to 0.0040.0040.004 nanometres?

  • 4×10−11 m4 \times 10^{-11}\text{ m}4×10−11 m
  • 4×10−12 m4 \times 10^{-12}\text{ m}4×10−12 m
  • 4×10−13 m4 \times 10^{-13}\text{ m}4×10−13 m
  • 4×10−10 m4 \times 10^{-10}\text{ m}4×10−10 m
