Choose the correct alternative and write it along with its allotted alphabet: If a ray of light passes from a denser medium to a rarer medium in a straight line, the angle of incidence must be

The average speed is equal to the magnitude of average velocity, for the motion of the particle along a straight line and in the same direction. then

The law of motion of a body moving along a straight line is x=1/2vt , x being its distance from a fixed point on the line at time t and v is its velocity there. Then

Ray optics is based on the assumption that light travels in a straight line. Diffraction effects (observed when light propagates through small apertures/slits or around small obstacles) disprove this assumption. Yet the ray optics assumption is so commonly used in understanding location and several other properties of images in optical instruments. What is the justification?

The equation of straight line passing through the point of intersection of the straight line 3x – y +2=0 and 5x - 2y +7=0 and having infinite slope is
