Question

Which is the correct ascending order of wavelengths?

Options

• `lambda_"visible"<lambda_"x-ray"<lambda_"gamma-ray"<lambda_"microwave"`

• `lambda_"gamma-ray"<lambda_"x-ray"<lambda_"visible"<lambda_"microwave"`

• `lambda_"x-ray"<lambda_"gamma-ray"<lambda_"visible"<lambda_"microwave"`

• `lambda_"microwave"<lambda_"visible"<lambda_"gamma-ray"<lambda_"x-ray"`

Answer 1

`bb(lambda_"gamma-ray"<lambda_"x-ray"<lambda_"visible"<lambda_"microwave")`

Explanation:

The wave having highest energy, has lowest wavelength as,

`"E"_γ > "E"_(x-"rays") > "E"_"visible" > "E"_"microwave"`

⇒ `lambda_gamma<lambda_"x-rays"<lambda_"visible"<lambda_"microwave"`
