As light rays travel from air into a glass prism, they deviate away from the normal.
False
When light travels from a rarer medium to a denser medium, it deflects towards the normal and when it travels from denser medium to a rarer medium, it deflects away from the normal.
In the air-glass model, air is a rarer medium and glass is a denser medium. So, when light rays travel from air to glass prism, they bend towards the normal.
