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 ...
Jena glass can scatter ultraviolet rays. It contains compounds like cerium oxide, which absorb and scatter UV radiation, making it useful in applications requiring UV protection, such as in optical lenses and scientific instruments.
