What type of image is formed on the retina?

Options

A. Virtual and inverted
B. Real and inverted
C. Vertically inverted image
D. Real and erect

Answer

To determine the type of image formed on the retina, we can follow these steps:

### Step 1: Understand the structure of the eye
The eye consists of several parts, including the cornea, lens, and retina. The lens focuses light onto the retina, which is located at the back of the eye.

**Hint:** Remember that the retina is a light-sensitive layer where images are formed.

### Step 2: Identify how light travels through the eye
When light rays from an object (like a tree) enter the eye, they are refracted (bent) by the lens. This bending of light is crucial for forming an image.

**Hint:** Think about how lenses work in general; they bend light to focus it.

### Step 3: Determine the nature of the image
The image formed on the retina is a result of the convergence of light rays. The lens inverts the image, meaning that the top of the object appears at the bottom of the image on the retina.

**Hint:** Recall that lenses can create inverted images, especially when they are convex lenses like the ones in our eyes.

### Step 4: Conclude the type of image
The image formed on the retina is real and inverted. A real image is one that can be projected onto a screen, and it is inverted because it appears upside down compared to the actual object.

**Hint:** Consider the terms "real" and "virtual" images; real images can be projected, while virtual images cannot.

### Final Answer
The type of image formed on the retina is **real and inverted**.
