What type of image (real or virtual) is formed on a cinema screen?

Answer

To determine the type of image formed on a cinema screen, we can follow these steps:

### Step 1: Understand the Types of Images
There are two main types of images formed by lenses and mirrors: real images and virtual images.

- **Real Image**: This type of image can be projected onto a screen. It is formed when light rays converge and can be captured on a surface.
- **Virtual Image**: This type of image cannot be projected onto a screen. It is formed when light rays appear to diverge from a point, and it cannot be captured on a surface.

### Step 2: Analyze the Formation of Images in a Cinema
In a cinema, the images we see on the screen are produced by projectors. The projector uses a lens system to focus light from the film onto the screen.

### Step 3: Determine the Nature of the Image
When the projector casts the image onto the cinema screen:

- The light rays from the film pass through the lens and converge to form an image on the screen.
- Since the image is formed by the convergence of light rays and can be captured on the screen, it is classified as a real image.

### Step 4: Conclusion
Therefore, the type of image formed on a cinema screen is a **real image**.
