Light behaves as a particle and consists of electrons; the electromagnetic spectrum includes only visible light.

Light behaves as a sound wave and consists of atoms; the electromagnetic spectrum includes infrared and ultraviolet only.

Light behaves as a solid and consists of molecules; the electromagnetic spectrum includes X-rays and gamma rays only.

Because blue light is scattered more than red light by air molecules

Because the sky is made of blue gases

Because the sun emits blue light
