The formation of day and night suggests the rectilinear propagation of light because when the Earth rotates on its axis, the sunlight falls on one side of the Earth creating day, while the other side facing away from the Sun is in darkness, creating night. This implies that light travels in straight lines from the Sun to the Earth, illuminating only the side facing the Sun at any given time.
Three essential conditions for shadow formation are a source of light, an object to block the light, and a surface to project the shadow onto. When light is blocked by an object, it creates an area behind the object where light cannot reach, resulting in a shadow being cast on the surface opposite the light source.
Dark nebulae formation, also known as absorption nebulae, do not produce their own light as they consist of dust and gas that block light from passing through. These nebulae are visible against a background of brighter stars.
The hot gas in star formation regions emits light due to the intense heating caused by compression and gravitational collapse. This heating excites the gas molecules and causes them to emit radiation across the electromagnetic spectrum, from infrared to ultraviolet. This light is what we observe as the glowing nebulae in star formation regions.
Emission nebulae are nebulae that are lit from within. They are made up of ionized gases that emit light of various colors depending on the elements present in the nebula. The light comes from the recombination of electrons with protons in the ionized gas.
Lenses are curved pieces of transparent material that refract, or bend, light rays as they pass through. They can converge or diverge light rays, which leads to the formation of images. Convex lenses (thicker in the middle) converge light to a focal point, while concave lenses (thinner in the middle) cause light rays to spread out.
Rectilinear propogation of light.
Light rays traveling through air or a vacuum demonstrate rectilinear propagation as they travel in a straight line. Sound waves can also exhibit rectilinear propagation in a homogeneous medium, as long as there are no obstructions or obstacles that cause the wavefront to bend or diffract.
Rectilinear propagation of light means that light travels in straight lines in a uniform medium, unless it encounters a change in medium or interacts with matter. This concept is a fundamental property of light behavior and is described by the laws of geometrical optics.

One example of rectilinear propagation of light in daily life is when sunlight enters a room through a rectangular window and travels in straight lines, casting shadows on the floor. Another example is when you use a flashlight to shine light down a long hallway, and the light travels in straight lines until it hits an object or surface.
Rectilinear propagation of light refers to the tendency of light to travel in straight lines in a uniform medium. This phenomena is evident in daily life when shadows are formed in a straight line, when light passes through a narrow opening, or when light reflects off a mirror.
Ibn al-Haytham, also known as Alhazen, a Persian scientist in the 11th century, is credited with discovering the rectilinear propagation of light. He conducted experiments and observations to understand how light travels in straight lines. His work laid the foundation for modern optics.
Rectilinear propagation of light means that light travels in straight lines through a uniform medium unless it encounters obstacles or changes in medium that cause it to change direction. This principle forms the basis of geometric optics and is used to predict how light behaves when it travels from one point to another.
Rectilinear propagation of light refers to light traveling in a straight line. This property is utilized in various applications, such as in optical communication systems to ensure minimal signal loss, in creating sharp images in photography, and in designing optical instruments like microscopes and telescopes for accurate visualization.
