पर्याय
`λ_"x-rays" < λ_"micro waves" < λ_"radio waves" < λ_"visible"`
`λ_"visible" < λ_"X-rays" < λ_"radio waves" < λ_"micro waves"`
`λ_"radio waves" < λ_"micro waves" < λ_"visible" <λ_"X-rays"`

उत्तर
`λ_"radio waves" < λ_"micro waves" < λ_"visible" <λ_"X-rays"`
Explanation:
∵ E = `(hc)/lambda`
The orderly arrangement of different parts of EM wave in decreasing order of wavelength is as follows:
`λ_"radio waves" > λ_"microwaves" > λ_"IR" > λ_"visible" > λ_"UV" > λ_"X-rays" > λ_"gamma"`
