If light is a wave then how come we can hear around a corner but not see around a corner?

The phenomenon of being able to hear around a corner but not see is due to the nature of sound and light waves. Sound waves are able to bend or diffract around objects, allowing us to hear them even if they are not directly in our line of sight. However, light waves are much shorter and cannot diffract as easily, so they do not bend around corners in the same way that sound waves do.
Light is an electromagnetic wave, meaning that it is made up of oscillating electric and magnetic fields. These fields travel through space at the speed of light and can be described by properties such as wavelength, frequency, and amplitude. Light waves are able to interfere with one another, creating patterns of light and dark areas, just like other types of waves.
Light travels through space as a transverse wave, meaning that the oscillating electric and magnetic fields are perpendicular to the direction of propagation. This allows light to travel in a straight line until it encounters an obstacle or changes medium, at which point it may be reflected, refracted, or absorbed.
The wavelength and frequency of light are inversely proportional to each other. This means that as the wavelength of light increases, the frequency decreases, and vice versa. This relationship is described by the equation: c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency.
The understanding of light as a wave has had a significant impact on our daily lives. It has allowed us to develop technologies such as radio, television, and the internet, which rely on the transmission of electromagnetic waves. It has also been crucial in the development of medical imaging techniques, such as X-rays, and has led to advancements in fields such as optics, astronomy, and telecommunications.
