Statement 1:
Some materials like glass are transparent to certain wavelengths of the electromagnetic spectrum and opaque to other wavelengths. The reason is the vibrational energies corresponding to which wavelengths pass through the object (like glass), the object seems transparent to them and opaque to the other.
Therefore, statement 1 is correct.
