Web15 Properties of Cathode rays: 1. Cathode rays travel in straight lines. 2. These rays are deflected by electric field. This is obvious because these rays are nothing but electrons. 3. These rays travel normally from the surface of cathode. 4. The direction of these rays is independent from the position of the anode. 5. Web(1) X-rays travel in straight line. (2) X-rays are invisible. When ordinary light is incident on the retina, it creates the sensation of vision; but for X-rays this does not happen. (3) It is …

WebMar 23, 2024 · The two main laws of ray optics are – the law of reflection and the law of refraction. From these laws, we can understand the behavior of optical devices such as telescopes and microscopes. Physical optics. The wave nature of light came into existence to explain the other properties of light such as diffraction and interference.

WebOct 8, 2024 · A ray is a line with an endpoint that extends infinitely in one direction. One of the most obvious examples is a sun's ray of light in space. Let's look at how light from the sun originates and... WebProperty 1: Cathode rays travel in a straight line and can cast sharp shadows. Property 2: Cathode rays are negatively charged. Property 3: Electric field and magnetic field deflect cathode rays. Property 4: They are produced at the cathode (negatively charged electrode) and travel towards the anode (positively charged electrode) in a vacuum tube. WebFigure 16.26 Rays of light enter a concave, or diverging, lens parallel to its axis diverge and thus appear to originate from its focal point, F. The dashed lines are not rays; they indicate the directions from which the rays appear to come. The focal length, ƒ, of a diverging lens is negative.An expanded view of the path taken by ray 1 shows the perpendiculars and the … tarif tol pemalang semarang 2022
