Approximation of Planck’s constant and work function using Photoelectric effect on the particle nature of light Abstract This experiment aims to demonstrate the particle nature of light by photoelectric effect. Stopping potential was measured against different intensities of yellow (λ = 578 nm) and green (λ = 546 nm) light from first order spectral lines of mercury. No significant relationship was observed for stopping potential and percent transmission. However‚ charging

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

integral part of our lives. This issue that “TV has bad effects on children “is a controversial one and can be approached from different angles due to its complexity; but in my opinion‚ a closer examination reveals that new generation is growing up addicted to the TV as it has never been truer than it is today . Especially‚ it has very bad effects on children. We can consider negative effects of TV on children in many aspects. First of all‚ it is bad for their health; second‚ it is harmful for their

mass that is gained or lost by the system will cause a change in momentum that is not the result of an external force. A different equation is necessary for variable-mass systems (see below). Newton’s second law requires modification if the effects of special relativity are to be taken into account‚ because at high speeds the approximation that momentum is the product of rest mass and velocity is not accurate. Newton’s second law states that an object will change acceleration if pushed or

As with any new technology‚ everyone is always talking about the negative side effects of the internet and saying how it ruins real face to face relationship‚ fills our minds with filth and damages our eyes and melts our brains. As usual it’s the panic mongers whose voices are most heard in the media and it’s gotten to such a point that people begin to feel guilty when they boot up their computer.

Video games can have bad effect on children Nowadays‚ more and more children play Video games because there is a computer at almost every home. Moreover‚ the number of Internet shop has increased and playing games becomes easier. However‚ I believe that Video games are not beneficial for children but they have an negative impact on them. This paper‚ therefore‚ will argue that Video games can have bad effect on children First of all‚ computer games take a lot of time of the children. If you

Well that’s what life would be like today without inventions from the 1940’s. Color TV‚ LEGOs‚ Microwaves and many other things that mankind uses today were invented in the 1940’s. Some of these things had great effects on mankind‚ some of them not. There were a lot of things that were invented in the 1940’s‚ the Jeep‚ Duct Tape‚ and Silly Putty are a few examples. These things have changed the world in many ways.
