Does reflection from an irregular surface obey the law of refraction?

Yes. The angle of reflection = the angle of incidence. This is where pictures of ray traces (see the link below) come in very handy, keeping in mind that a ray trace is a very small (the magical physics *very small*) portion of the light that is falling on the mirror at a very small period of time. It works easiest for curved mirrors if the mirror has the reflective surface on the front (where the light is coming from) so we don't have to play with the refractive equations of the intermediate media. The mathematics of the angle of incidence and reflection is fairly easy for linear equation surfaces, like shperical, parabolic and hyperbolic, but gets a little more involved for nonlinear surfaces (like wrinkled tin foil).

Explain how both kinds of reflection obey the law of reflection?
The angle of reflection equals the angle of incidence. In regular reflection, parallel rays strike are reflected from smooth surface at the same angle in diffuse reflection, parallel rays strike and are reflected from a bumpy surface at different angles.
Why rays at zero incidence do not get refracted?
Rays at normal incidence ... perpendicular to the interface ... obey the same law of refraction that rays at any other angle do. I won't write the equation of refraction here, because you probably already know what it looks like, and if you're a little rusty, you can easily find it on line or in your Physics text as "Snell's Law". The law of refraction relates the angles with respect to the normal in each medium to the index of refraction in each medium. In the formula, the angles are referenced in terms of their sines. If the incident ray is perpendicular to the interface, then the sine of the angle of incidence is zero. Then, regardless of the relative optical densities of the two media, the sine of the angle of refraction is also zero. The ray that arrives along the normal is refracted after all, through an angle of zero.
When was ...And They Obey created?
...And They Obey was created on 2002-02-25.
Will any of the chlorine oxides obey the octet rule?
No chlorine oxides will obey the octet rule.
What atoms dont always obey the octet rule?
Hydrogen does not obey the octet rule. Boron does not always obey the octet rule and in fact forms Lewis acids such as BF3 which only has 6 electrons.

Does diffuse reflection obey the law of reflection?
no
All waves obey the law of reflection?
yes
Do convex and concave mirrors obey the law of reflection?
yes
Do Only transverse waves obey the law of reflection?
Erection.
Do a convex and concave mirrors obey the law or reflection Explain?
Yes it does.
Why do curved mirrors obey the law of reflection?
they are made out of reflective material, and just reflect in a different direction
What is the relationship between radiowave and electromagnetic wave?
Actually, a radio wave is an electromagnetic wave( transverse, speed of 3.0x108, do not require a material medium to travel so can travel through a vacuum, carry no charge, can be produced and absorbed by matter and obey the laws of refraction and reflection) In the electromagnetic spectrum, radio waves have the longest wavelength and lowest frequency.

Is the verb obey to or just obey?
The verb is merely, obey. I obey, you obey, he, she, it obeys. One may be obedient to someone, but one does not "obey to" someone.
