Light is considered as a transverse wave because it travels

Light is a form of electromagnetic radiation that travels in waves. There are two types of waves: longitudinal and transverse. Longitudinal waves are waves in which the particles of the medium vibrate parallel to the direction of wave propagation, while in transverse waves, the particles vibrate perpendicular to the direction of wave propagation. Light is considered a transverse wave because it travels in a direction perpendicular to the plane containing the electric and magnetic fields. The electric and magnetic fields are at right angles to each other, and both are perpendicular to the direction in which the light is traveling. The oscillation of the electric and magnetic fields is perpendicular to the direction of travel of the wave, which makes it a transverse wave. Moreover, light can travel through space without the need for a medium. Unlike sound waves, which require a medium such as air or water to propagate, light can travel through a vacuum. This is because light is made up of electromagnetic waves, which do not require a medium to travel through. So, the answer is "in a direction perpendicular to the plane containing the electric and magnetic fields".
