Options

A. transverse
B. of high frequency
C. longitudinal
D. reflected

Explanation

To solve the question "Light waves can be polarised as they are," we need to understand the nature of light waves and the concept of polarization. Here’s a step-by-step solution:

### Step 1: Understand the Nature of Light Waves
Light waves are electromagnetic waves that consist of oscillating electric and magnetic fields. These fields oscillate perpendicular to each other and to the direction of wave propagation.

**Hint:** Remember that light waves are transverse waves, which means their oscillations are perpendicular to the direction of travel.

### Step 2: Define Polarization
Polarization of light refers to the orientation of the oscillations of the electric field vector. In unpolarized light, the electric field oscillates in multiple planes. However, in polarized light, the electric field oscillates in a single plane.

**Hint:** Think about how the orientation of the electric field can be restricted to a single direction to achieve polarization.

### Step 3: Identify Conditions for Polarization
Light waves can be polarized under certain conditions, such as reflection, refraction, or by passing through a polarizing filter. This is because the transverse nature of light allows for the selective alignment of the electric field vectors.

**Hint:** Consider the methods used to polarize light, such as using polarizing filters or reflecting light off surfaces at specific angles.

### Step 4: Conclude the Answer
Since light waves are transverse waves, they can be polarized. This is due to the fact that their vibrations can be restricted to a single plane, which is the essence of polarization.

**Hint:** Recall that the transverse nature of light is what allows for the phenomenon of polarization to occur.

### Final Answer
Light waves can be polarized as they are transverse waves, where the vibrations are perpendicular to the direction of wave propagation.
