To explain: Whether the lens of human eye, finger nails and tooth are opaque, translucent or transparent.
Answer to Problem 5R
The lens of human eye is transparent.
Finger nail is translucent.
Skin is opaque.
Tooth is opaque.
Explanation of Solution
Introduction: Wave is the repetition movement in which energy is transferred through space or matter. Light is a type of wave that carries energy through matter or space.
The lens of human eyes is the biconvex crystal type structure. It is transparent in nature which allows the lights to pass.
Finger nail partially allows light. So, it is translucent because translucent materials transmit light and also absorb it (or scatter it).
Skin does not allow light through it. So, it is opaque because opaque material absorbs and also, reflects light. Because of this a person cannot see object through it.
Tooth does not allow light through it. So, it is opaque because opaque material absorbs and also, reflects light. Because of this a person cannot see object through it.
