Arrange the following in the ascending order of wavelength (λ): (A) Microwaves (λ₁) (B) Ultraviolet rays (λ₂) (C) Infrared rays (λ₃) (D) X-rays (λ₄) Choose the most appropriate answer from the options given below: (a) λ₄ < λ₃ < λ₂ < λ₁ (b) λ₄ < λ₂ < λ₃ < λ₁ (c) λ₃ < λ₄ < λ₂ < λ₁ (d) λ₄ < λ₃ < λ₁ < λ₂

Answer: (b). Ascending wavelength: X-rays < UV < IR < microwaves. So λ₄ < λ₂ < λ₃ < λ₁, the answer is (b).
