A sinusodal wave travels along with.The time for a praticular poin as move from maximum displace ment to zerodisplacement is 178ms.The wavelength of the wave is 1.38m.Find the period ,the frequency and the speed of the wave
Optics
a glass prism in the shape of a quarter-cylinder lies on a horizontal table.a uniform, horizontal light beam falls on its vertical plane surface, as shown in the figure. if the radius of the cylinder is R=5cm and the refractive index of the glass is n=1.5,where , on the table beyond the cylinder, will a path of light be found?
Optics
If your vision somehow began to increase so that you could see higher and higher frequencies beyond visible light, what type of wave would you be able to perceive first?
Optics
will the bending of light be more or less for a medium with high refractive index?
