Option (B) is correct .i.e. atoms are made of particles that have negative charge.

Further explanation:

Using cathode ray tube, <u>J.J Thomson</u> found that something emits from the negative plate (called as cathode) and goes towards the positive plate (called as anode), and on applying zinc sulfide (also called phosphor) coating on the perforated anode, it shows green fluorescence at some particular values of pressure and temperature.

William Crookes called them the cathode rays as were originated from cathode. Further, Atoms are overall neutral having equal amounts of positive and negative charge as he explained in his plum pudding model.

Although, electrons in atoms have varying energy but this was not confirmed by J.J. Thomson, also electrons can’t be inside nucleus because this would make atoms very unstable.

Some of the properties of those cathode rays are as follows:

(1). They are made up of material particles (they made the light wheels rotate that come in their path).

(2). The green fluorescence was also observed when he putted two more plates perpendicular to the earlier path and the rays followed a curved path towards the new anode.

(3). They has an ionizing property (they ionizes the gas present in the cathode ray tube, through which they pass).

Thus, <u>Option (B) is correct because the cathode rays are emitted from the metallic plate which’s atoms have particles having negative charge.</u>

A Ray of light in air is incident on an air to glass boundary at an angle of 30. degrees with the normal. If the index of refrac
elena55 [62]

Answer:

A

Explanation:

Snell's law states:

n₁ sin θ₁ = n₂ sin θ₂

where n is the index of refraction and θ is the angle of incidence (relative to the normal).

The index of refraction of air is approximately 1.  So:

1 sin 30° = 1.52 sin θ

θ ≈ 19°
