Out of speed, frequency and wavelength, name the parameter (s) which remain the same on reflection.
What happens to the frequency, wavelength and speed of light that crosses from a medium with index of refraction mu_1 to one with index of refraction mu_2 ?
Obtain a relation between speed, frequency and wavelength of a wave.
You send a travelling wave along a particular string by oscillation one end. If you increase the freuency of the oscillation, do (a) the speed of the wave and (b) the wavelength of the wire increase, decrease, or remain the same? If, instead, you increase the tension in the string, do (c) the speed of the wave and (d) the wavelength of the wave increase, decrease, or remain the same?
Calculate the frequency and wavelength of a light wave in a medium of refractive index 1.6. Given that the wavelength of light wave in air is 6,400 Å .
When light moves from one medium to another (i) the frequency of light remains same and wavelength changes (ii) refractive index of a medium is the ratio of speed of light in vacuum and speed of light in medium (iii) refractive index of a medium is the ratio of wavelength of light in vacuum and wavelength in medium (iv) for denser medium, the value of refractive index is larger
Two interferring waves have the same wavelength, frequency and amplitude. They are travelling in the same direction but 90^(@) out of phase compared to individual waves. The resultant wave will have the same.
A light ray of frequency v and wavelength lambda enters a liquid of refractive index 3//2 . The ray travels in the liquid with
