What are the properties of black light and how is it different from other types of light?
Black light, also known as ultraviolet light, has unique properties that set it apart from other types of light. It emits ultraviolet radiation, which is invisible to the human eye but can cause certain materials to fluoresce or glow. Black light is different from visible light in that it has a shorter wavelength and higher energy, making it useful for applications such as detecting counterfeit money, identifying bodily fluids, and creating special effects in entertainment.

What object absorbs light?
Objects like black holes absorb light due to their immense gravitational pull. Other examples include black or dark-colored materials with high absorbance properties, such as charcoal or black fabric.
Why is a black hole called a black hole and what makes it different from other celestial objects?
A black hole is called a black hole because it is a region in space where gravity is so strong that nothing, not even light, can escape from it. This makes it appear black or invisible. What makes black holes different from other celestial objects is their extreme density and gravitational pull, which can distort space and time around them. This creates unique properties such as an event horizon, where anything that crosses it is pulled into the black hole.
What colors are absorbed by black light?
Black light emits ultraviolet (UV) light, so it typically excites fluorescent materials that absorb UV light and re-emit visible light. Fluorescent colors that appear bright under black light include neon colors like pink, green, orange, and yellow. Other colors without fluorescent properties may appear muted or black under black light.
How light and dark band are isotropic and anisotropic?
Light bands are isotropic because they have uniform optical properties in all directions, meaning that they exhibit the same behavior regardless of the direction of light. On the other hand, dark bands can be anisotropic because their optical properties vary depending on the direction of light, resulting in different behaviors when light is incident from different angles.
Why shadow is black in color?
there are some preticullar properties of different colours. like all colours, black colour also has its own property it is, it absorbs colours so, when the white light i.e. when it touches a person, it turns into black (like when white light enters prism,it turns into 7) colours and absorbs other colours, and the shadow formed is of black colour.
Are isotopes different in terms of their chemical properties?
A difference of chemical properties is observed for light elements; for other elements these differences are extremely small.

Explain the law of reflaction using a diagram?
Unfortunately, reflaction is one letter away from reflection and refraction, two different properties of light and other electromagnetic radiation. The two phenomena have different properties, and their diagrams would be different.

What are the 3 properties of light?
The three properties of light are reflection, refraction, and absorption. Reflection occurs when light bounces off a surface, refraction is the bending of light as it passes through different materials, and absorption is the process of light being taken in and converted into other forms of energy.
In what sense is a black hole actually black and how does this characteristic contribute to its unique properties and behavior?
A black hole is black because its gravity is so strong that not even light can escape from it. This characteristic contributes to its unique properties and behavior by causing it to have a powerful gravitational pull that can distort space and time, and also by allowing it to absorb matter and energy without emitting any light or other forms of radiation.
How do photons of various types of light differ from each other?
Photons of different types of light differ in their energy levels and wavelengths. For example, blue light has higher energy and shorter wavelengths than red light. This variation in energy and wavelength accounts for the different colors and properties of light.
What is the sensation produced by light as it strikes the eye a tint other than black or white?
Anything other than black, white, or different shades of gray is normally known as "color".
What is the difference between a fluorophore and a chromophore in terms of their light absorption and emission properties?
A fluorophore is a type of chromophore that can absorb light at one wavelength and emit light at a different wavelength. Chromophores, on the other hand, can absorb light but may not necessarily emit light.
