From a rigid support, a rope of mass M is hung vertically. To the free end of this rope, a wooden block of mass m is attached. At the lower end of rope, a transverse pulse of wavelength `lambda` is produced. What will be wavelength of pulse when it reaches the top of the rope ?

Explanation

To solve the problem, we need to determine the wavelength of a transverse pulse as it travels up a vertically hung rope with a mass attached to its free end. We will follow these steps:

### Step 1: Understand the system
- We have a rope of mass \( M \) hanging vertically from a rigid support.
- A wooden block of mass \( m \) is attached to the free end of the rope.
- A transverse pulse is produced at the lower end of the rope with an initial wavelength \( \lambda \).

### Step 2: Determine the tension in the rope
