Perpendicular
No, Mechanical waves means that the waves require a medium in order to pass through. For instance, sound is a mechanical wave because it requires the air to travel through (or any material -- such as water). Light waves are electromagnetic waves because they produce an oscillating electric/magnetic field as it travels. Also because it requires no medium to travel through, this is why the sun's light may reach us here on earth. (Note: it was previously thought that the medium in space which allowed light to travel through, this was referred to as the ether - this is false, space is a vacuum.)
why is the sun ray more concectrated on the equator
incident ray i think
X-ray

A light ray is always at right angles to its wave front.
A ray is normal and perpendicular to the wave front. Shortly, that's the difference.
Ray Allen, the basketball player, has never publicly discussed his sexual orientation.
Ray Dalton, singer and songwriter, has never discussed his sexual orientation in public.
Ray Price never publicly discussed his sexual orientation, but all indications are that he was straight.
Ray goes along a straight line. Wavefront spreads equally in all directions. Ray is always normal to the wavefront. Based on ray concept the first law of reflection will be stated as: The incident ray, the reflected ray and the normal all the three lie in the same plane. But by wave front concept we have to state the same with an alteration The incident wavefront, the reflected wavefront and the reflecting surface all the three are perpendicular to the same plane.
-- a radio wave -- a heat wave -- a yellow wave -- a blue wave -- an ultraviolet wave -- an X-ray -- a gamma ray
No, an X-ray is not a mechanical wave. An X-ray is an electromagnetic wave. However, in polar molecules, an X-ray can cause the molecule to vibrate rapidly, just like a microwave oven can.
Gamma ray
Straight.
No, he's Straight.
A gamma ray is an electromagnetic wave. It has the highest frequency (and energy) as well as the shortest wavelength on any wave on the electromagnetic spectrum.
