When a person enters a dark room from a bright area, initially they do not see clearly due to the slow adaptation of their eyes to low light conditions. Over time, their eyes adjust through a process called dark adaptation, ...

When light waves pass from air to glass, only the wavelength and velocity are affected. The frequency remains constant as it depends on the source. The wavelength decreases in glass due to its higher refractive index, while the velocity decreases ...
Blue light has the highest energy among the options given. Light energy is directly proportional to its frequency and inversely proportional to its wavelength. Blue light has a shorter wavelength and higher frequency compared to green, red, and yellow light, ...
Plants absorb intensely blue and red light. These wavelengths are crucial for photosynthesis, as they are efficiently absorbed by chlorophyll, the pigment responsible for capturing light energy. This absorption drives the process of converting light energy into chemical energy used ...
The process of separation of white light into its different colors is called dispersion. This phenomenon occurs when light passes through a medium, such as a prism, causing different wavelengths (colors) of light to refract at different angles and spread ...
