- Light enters the eye through the cornea: The cornea is the eye's outermost layer, and it helps focus incoming light.
- The anterior chamber is filled with aqueous humor: This chamber, located between the cornea and the iris, contains aqueous humor, a clear fluid that nourishes the eye and maintains pressure.
- The pupil changes in size to let more or less light enter the eye: The pupil adjusts its size in response to light intensity, contracting in bright light and dilating in dim light.
All statements are true, so the correct answer is D: All of the above.
Which of the following statements is true?a)Light enters the eye throu...
Light enters the eye through the cornea
- The cornea is the clear, dome-shaped front surface of the eye.
- It is responsible for most of the eye's focusing power.
- When light enters the eye, it first passes through the cornea.
The anterior chamber is filled with vitreous humor
- The anterior chamber is the front part of the eye between the cornea and the lens.
- It is filled with a clear, watery fluid called aqueous humor.
- The vitreous humor, on the other hand, fills the larger space behind the lens, known as the vitreous chamber.
The pupil changes in size to let more or less light enter the eye
- The pupil is the circular opening in the center of the iris, which is the colored part of the eye.
- The size of the pupil can change depending on the amount of light present.
- In bright conditions, the pupil constricts or becomes smaller to limit the amount of light entering the eye.
- In dim conditions, the pupil dilates or becomes larger to allow more light to enter the eye.
All of the above
- The correct answer to the question is option 'D' - all of the above.
- This means that all three statements are true.
- Light enters the eye through the cornea, the anterior chamber is filled with aqueous humor, and the pupil changes in size to regulate the amount of light entering the eye.
In summary, light first enters the eye through the cornea, then passes through the anterior chamber filled with aqueous humor, and finally reaches the pupil, which can change in size to control the amount of light entering the eye.
