Which color light is diffracted at a greater angle, red light or yellow light?
red light
red
To determine which color light is diffracted at a greater angle, we can look at the phenomenon of diffraction and use the concept of wavelength.
Diffraction refers to the bending of waves around obstacles or through narrow slits. When light passes through an opening or encounters an edge, it undergoes diffraction and spreads out. The amount of diffraction depends on the wavelength of the light, with longer wavelengths diffracting more than shorter wavelengths.
In the visible light spectrum, red light has a longer wavelength than yellow light. Therefore, red light is diffracted at a greater angle compared to yellow light.
If you want to explore this further, you can perform a simple experiment at home. Take a narrow slit or small opening and shine a beam of red light and yellow light through it onto a screen or a wall. You will notice that the red light spreads out more, indicating a larger diffraction angle than the yellow light.
