An astronomical satellite detects four discrete wavelengths of electromagnetic radiation emitted during a cosmic burst event:

λ1=2.0×10−12 m \lambda_1 = 2.0 \times 10^{-12}\text{ m} λ1​=2.0×10−12 m λ2=3.0×10−10 m \lambda_2 = 3.0 \times 10^{-10}\text{ m} λ2​=3.0×10−10 m λ3=2.0×10−8 m \lambda_3 = 2.0 \times 10^{-8}\text{ m} λ3​=2.0×10−8 m λ4=5.0×10−5 m \lambda_4 = 5.0 \times 10^{-5}\text{ m} λ4​=5.0×10−5 m

Which of the following options correctly classifies these wavelengths into their respective regions of the electromagnetic spectrum?

λ1\lambda_1λ1​: Gamma ray; λ2\lambda_2λ2​: X-ray; λ3\lambda_3λ3​: Ultraviolet; λ4\lambda_4λ4​: Infrared

λ1\lambda_1λ1​: Infrared; λ2\lambda_2λ2​: Ultraviolet; λ3\lambda_3λ3​: X-ray; λ4\lambda_4λ4​: Gamma ray

λ1\lambda_1λ1​: Gamma ray; λ2\lambda_2λ2​: Ultraviolet; λ3\lambda_3λ3​: X-ray; λ4\lambda_4λ4​: Infrared

λ1\lambda_1λ1​: X-ray; λ2\lambda_2λ2​: Ultraviolet; λ3\lambda_3λ3​: Infrared; λ4\lambda_4λ4​: Microwave
