This in turn does not add a greater gravitational pull downward due to the greater level of mass. Which means that the string has added tension, which pulls the cart faster in table number 2. How does the acceleration in Data Table 3 compare with that of Data Table 1? Why do we observe this difference? In data table 3 the rate of
This effect was proved experimentally in the 1960s.The converse of this phenomenon is also existing. The observed wavelength of a photon falling into a gravity well will be become shorter, or gravitationally ‘blueshifted’, because it will gain
This occurs because the angle at which the rays hit the boundary (called the angle of incidence) determines the angle at which the rays will refract (called the angle of refraction). Light rays are measured from the normal, not from the medium boundary. Snell’s law shows a mathematical relationship between the light’s angles of incidence and refraction, and the refractive indices of the media it travels through: n1sinθ1=n2sinθ2 Where: θ1=angle of incidence θ2=angle of refraction n1=index of refraction of first medium
This is because if the lens is larger, it can gather more light and therefore more of the image. This will also affect the brightness of the image produced. The magnification of the image is proportionate to the ratio between the focal length of the object and the focal length of the eyepiece lens. The amount of light that can be gathered is increased by 4 times if the diameter of the lens is doubled. The Descartes formula can be used to find out the location and magnification of the image formed.
The tool used in the experiment is based on the principle of light dispersion by the prism into its spectrum. The radiation emitted by a black object is passed through the gap to obtain a narrow beam of wave. The waves are then dispersed according to their respective wavelengths. To measure the intensity and wavelength of each spectrum, a detector can be shifted according to the angle of the deviation of the dispersed wave
Theoretical Framework According to the Helmholtz theory of accommodation, the eye adjusts it’s lens or cornea to increase or decrease optical power to adjust to the distance of what a person is trying to see. In conclusion with relation to the study, the eye shape affects the amount and direction of light for peripheral vision since only the cornea can use the ciliary muscle to adjust it’s own shape. Based on this theory, the study revolves around the idea that the shape will affect the range of periphery. Thus, where the study is derived from. C. Conceptual
The physicists examined the intensity of radiation for certain wavelengths. The tool used in the experiment is based on the principle of light dispersion by the prism into its spectrum. The radiation emitted by a black object is passed through the gap to obtain a narrow beam of wave. The waves are then dispersed according to their respective wavelengths. To measure the intensity and wavelength of each spectrum, a detector can be shifted according to the angle of the deviation of the dispersed wave
Visible sunlight is free to propagate into space above the photosphere and its energy escapes the Sun entirely. The decreasing amount of H− ions which absorb visible light easily is the reason for the change in opacity. The extent of ionization is about 3% in photosphere leaving almost all of the hydrogen in atomic form. The photosphere is not fully
Shekhar and Pervaiz  studied the effects of Rotation, Magnetic field and initial stresses on propagation of Plane waves in transversely isotropic dissipative half space. Cowin and Nunziato  discussed the problem of linear elastic materials with voids. Dey and Addy  investigated the reflection of
Aim To investigate the effects of radiation on temperature using the greenhouse model. Hypothesis As the greenhouse models are exposed to radiation, both will result in an increase of temperature with the temperature in the closed-ended model increasing at a faster rate than the open-ended model. Variables Independent: The open end and the closed end of the model Dependent: The temperature of two different conditions Controlled: The distance between the lamp and the greenhouse models, the same type of light, the amount of clay to seal the air and the amount of heating time. Method 1. 3 microscope slides were fitted together to form a prism, resembling the greenhouse model, shown below.
