Question

which explains why the fork looks different under water? light cant pass through the glass the wavelength of light lengthens light is refracted at an angle the amount of light increases when going through water

Explanation:

The phenomenon of the fork looking different underwater is due to light refraction. When light travels from air to water (different mediums), it bends (refracts) at an angle, causing the apparent position of the fork to change. The first option is wrong as light can pass through glass. The second is wrong as wavelength doesn't lengthen in this context. The fourth is wrong as light amount doesn't increase in water. So the correct reason is light refracting at an angle.

Answer:

C. light is refracted at an angle
