If light hits a smooth hard surface at a 35 degree angle at what angle will it reflect of the surface?
By convention angles are measured from the normal to the reflecting surface. The angle of incidence, 35 degrees, is equal to the angle of reflection. In this case 35 degrees. The answer is 35 degrees.
What is a line perpendicular to a reflecting surface called?
a tangent
Has a reflecting surface that curves outward?
A convex reflector.
What are the conditions necessary to hear echo?
The reflecting surface must be sufficiently smooth and shaped such that the sound is reflect back and not dispersed. Sound travels at approx 340 metres per second and the average human brain easily can distinguish sounds that are 1/2 second apart. That means the sound must travel at least 170 metres so that the reflecting surface must be half that distance away. While a greater distance will create a more distinctive echo, the strength of the returning sound fall off rapidly (at twice the square of the distance to the reflecting surface). In normal circumstances 170 metres (= approx 500 feet) is a good distance. A cave or convex reflecting surface will allow a greater distance.
Which smooth surfaces reflect light?
Any smooth surface will reflect light. The better question is "How much light does each kind of smooth surface reflect?"
What is a common reflecting surface that is smooth?
Glass or water.

What is the definition of glossy?
Smooth and shining; reflecting luster from a smooth surface; highly polished; lustrous; as, glossy silk; a glossy surface., Smooth; specious; plausible; as, glossy deceit.
In which direction do light rays reflecting off a smooth surface reflect?
Newton: " the angle of incidence equals the angle of refraction."
Which is the Metal in reflecting telescope?
Usually aluminum. It is normally deposited as a vapour to get an incredibly smooth surface. In small home-made telescopes, they use silver.
Is the force is greater on a smooth surface or on a rough surface?
smooth surface.
A mirror with a reflecting surface that caves inward is said to be?
A CONCAVE mirror is a mirror with a reflecting surface that curves inward.
What are the condition required for occurrence an echo?
A true echo is one in which the source of sound is located in close vicinity to the receiver. You will requirea pulse of sound,a reflecting surface which is more than 17.2 metres from the sound source,the reflecting surface must be sufficiently smooth and at right angles to the direction of travel of the sound waves.
Does a basketball roll faster on a smooth surface or a rough surface?
on a smooth surface

What is a good reflecting surface?
a mirror
