CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
B, A, C, D, E
Electromagnetic Radiation Frequency Order
The question asks to arrange specific types of electromagnetic radiation based on their frequency, in increasing order.
Electromagnetic Spectrum Basics
The electromagnetic (EM) spectrum categorizes EM radiation by frequency ($f$) and wavelength ($\lambda$). These are inversely proportional, related by the speed of light ($c = \lambda f$). Higher frequency means shorter wavelength.
The general order of increasing frequency (and decreasing wavelength) is:
- Radio waves
- Microwaves
- Infrared radiation
- Visible light
- Ultraviolet radiation
- X-rays
- Gamma rays
Identifying the Radiation Types
The specific types mentioned in the question are:
- A. Microwave
- B. Radio wave
- C. Visible light
- D. X-ray
- E. Gamma rays
Determining the Correct Sequence
Arranging the given types in order of increasing frequency:
- Radio wave (B): Lowest frequency among the given options.
- Microwave (A): Higher frequency than radio waves.
- Visible light (C): Higher frequency than microwaves.
- X-ray (D): Higher frequency than visible light.
- Gamma rays (E): Highest frequency among the given options.
Therefore, the correct sequence of increasing frequency is B, A, C, D, E.
Matching the Options
The sequence B, A, C, D, E corresponds to the option listing Radio wave, Microwave, Visible light, X-ray, Gamma rays in increasing frequency order.
This matches Option 2.
