    As you know,the set of light wavelengths that a material is transparent to,is sth dependent on the properties of the material.My question is,can we find a material
    which is transparent to a specific wavelength range?
    For example,I want a material,which,among the visible light wavelengths,is transparent to only red light.How can I find out what material is that?

    There are many optical filters which can do that.
