wave optics 12 |wavefront L-1| JEE/neet /cbse
**Wavefront and Ray** are two fundamental concepts in the study of wave optics. Here's a breakdown of each concept:
### 1. **Wavefront**
- **Definition**: A wavefront is an imaginary surface that connects all points of a wave that are in the same phase of vibration.
- **Shape**: The shape of a wavefront depends on the nature of the source:
- **Point source**: The wavefronts are spherical in shape.
- **Line source**: The wavefronts are cylindrical.
- **Plane wave**: If the source is at infinity, the wavefronts become flat or planar.
- **Types of Wavefronts**:
- **Spherical Wavefront**: Produced by a point source of light.
- **Cylindrical Wavefront**: Produced by a linear source of ligh...

In physics , a compound microscope is an optical device that uses multiple lenses to magnify small objects or details that are too tiny to be seen with the naked eye. It typically consists of two main lenses: the objective lens and the eyepiece (ocular lens) . The objective lens is placed near the specimen, and it first magnifies the object. The eyepiece then further magnifies the image formed ...

Просмотров 21День назад
A simple microscope is an optical instrument that uses a single lens to magnify small objects. The basic physics of a simple microscope is based on the principles of refraction and magnification . Key Concepts: 1. Refraction : When light passes through a lens, it bends (refracts). A convex lens (which is thicker in the middle than at the edges) bends light rays in such a way that they converge ...

The power of a lens is a measure of its ability to converge or diverge light. It is defined as the reciprocal of the focal length of the lens, and its unit is the diopter (D) . The formula for the power \( P \) of a lens is: \[ P = \frac{1}{f} \] Where: - \( P \) is the power of the lens in diopters (D). - \( f \) is the focal length of the lens in meters (m). Key points: 1. Positive Power (Con...

The thin lens formula can also be expressed in terms of the object distance \(u\) and the image distance \(v\). This is commonly used in optics, where: - \( u \) is the object distance (distance from the object to the lens), - \( v \) is the image distance (distance from the image to the lens), - \( f \) is the focal length of the lens. The thin lens equation in terms of \(u\) and \(v\) is: \[ ...

A thin lens is a lens with a very small thickness compared to its focal length. It is an idealized lens where the thickness is negligible, and the light rays pass through the lens from one side to the other without significant deviation due to the lens material. Types of Thin Lenses There are two main types of thin lenses: 1. Convex lens (Converging lens) : Thicker at the center than at the edg...
