The other neighbouring wavelengths will be present with less intensity. There will also be certain wavelengths which satisfy the condition of minima. Such wavelengths of colors will be absent from the reflected light. AS result the point of the film will appear ...

WebIn this article I will show examples of underexposed photos and describe the pros and cons of underexposure. Generally, an underexposed photo where the camera lets in too little light is dark, with the subject not seen clearly, little detail in the shadows, light sources appearing dimmer, and the image as a whole looking off. Let’s discuss. Web1 Answer. Thin film is the film whose thickness is of the order of wavelength of the light which is used to expose it. When a thin film is exposed to white light from an extended …

The lens in this photo appears blue-violet in this photo taken off-axis (see below for an explanation). On axis, the lens looks dark – which means that little light is being reflected, so most is being admitted into the camera – which in turn is the chief purpose of non-reflective coatings: they make … phillips alliance refineryThin-film interference explains the multiple colors seen in light reflected from soap bubbles and oil films on water. It is also the mechanism behind the action of antireflection coatings used on glasses and camera lenses .
