Fluorescein staining
fluorescein staining
If you stained the eye of a patient with two marginal corneal ulcers using fluorescein, you would see bright green staining in the areas of the ulcers. This is because fluorescein adheres to damaged epithelial cells, highlighting the defects in the corneal surface. The surrounding healthy corneal tissue would appear normal and not fluoresce, making the ulcers more pronounced. Additionally, you might observe a potential underlying conjunctival or limbal involvement depending on the severity of the ulcers.
um really bright
The Moon appears bright at night because it reflects sunlight. Planets appear bright due to the reflection of sunlight off their surfaces, as well as their own internal heat that emits light. Additionally, planets are much closer to Earth than stars, making them appear brighter in the night sky.
If the bright star is located farther away from Earth than the less bright star, it will appear dimmer due to the inverse square law of light intensity. The amount of light reaching Earth decreases with distance, so a closer, less bright star can appear brighter than a further, brighter star.
you might have aids =(
because of the suns bright light shining on the surface of the moon
Earth's nearest neightbor
Space stations can appear bright in the night sky because they reflect sunlight off their solar panels and metal surfaces. This reflection can make them appear as bright, moving objects as they orbit the Earth.
Yes, white is considered a bright color because it reflects all wavelengths of light, making it appear bright and often associated with cleanliness, purity, and simplicity.
It depends on its intrinsic brilliance and its distance from the observer
