1 metre is the length of path travelled by light in vacuum during a time Interval of

Can light travel in vacuum ?

There is a equilateral prism of refractive index 3 on which a light ray is incident normally on one face as shown in the figure. Find the length of the path traveled by the light ray inside the prism.

The speed verses time graph for a particle is shown in the figure. The distance travelled (in m) by the particle during the time interval t = 0 to t = 5 s will be __________

Derive an expression using the method of dimensions, the distance travelled by a body during an interval of time t, if its initial velocity is u and uniform acceleration is a.

A particle moves along a horizontal path, such that its velocity is given by v = (3t^2 - 6t) m//s, where t is the time in seconds. If it is initially located at the origin O, determine the distance travelled by the particle in time interval from t = 0 to t = 3.5 s and the particle's average velocity and average speed during the same time interval.

A ray of light passes normally through a slab (mu=1.5) of thickness t. If the speed of light in vacuum be C, then time taken by the ray to go across the slab will be

The velocity-time graph of a moving object is given in the figure. Draw the acceleration versus time and displacement versus time graph. Find the distance travelled during the time interval when the acceleration is maximum . Assume that the particle starts from origin.

The speed of light in vacuum is 3 xx 10^8 ms^(-1)

It is stated in the previous problem that a pilse travels from the bottom to the top of a hanging rope of length L in the time interval Delta=2sqrt(L/g) . Use this result to answer the following question. (It is not neccesary to set up any new integrations.) (a) over what time interval does a pulse travel halfway up the rope? Give your answer as a fraction of the quantity 2sqrt(L/g) . (b) A pulse starts travelling up the rope. how far it travelled after a time interval sqrtL/g) ?

Assertion : The average speed of an object is greater than or equal to the magnitude of the average velocity over a given time interval. Reason : The two are equal only if the path length is equal to the magnitude of displacement.
