WebNov 15, 2024 · (The angle of refraction is defined as the angle between the source-receiver direction and the actual ray trajectory at the receiver.) Figure 3. ( a) Modal phase speed profile along the y -axis for the first mode at a frequency of 55 Hz and ( b) the corresponding modal rays in the horizontal plane. WebThe main cause of refraction of light is the difference in the velocity of light when it enters different mediums. The speed of light in air is faster than that of water. Thus, the speed of light increases when it travels from water to air, and similarly, the speed decreases when it travels from air to water. korekiyo shinguji voice actor english
