How does laser light differ from natural light?

Laser light is more intense
Laser light consists of many wavelengths
Laser light consists of just one wavelength
Laser light cannot be seen by the naked eye

The correct answer is: Laser light consists of just one wavelength

Laser light differs from natural light in that it consists of just one specific wavelength, whereas natural light contains a range of different wavelengths that combine to form white light. This is what gives natural light its variety of colors, whereas laser light only produces a single color. Option A is incorrect because although laser light appears more intense due to its concentrated beam, both types of light can have the same intensity. Option B is incorrect because laser light only consists of one wavelength, making it different from natural light which contains many wavelengths. Option D is incorrect because laser light can be seen by the naked eye, but due to its high intensity and focused beam, it can be damaging to the eyes if looked at directly.
